If the ball thrown downward had the same initial speed as the ball thrown upward, it would have achieved exactly the same velocity when it hit the ground. If, on the other hand, the upward thrown ball had a higher initial speed, it would then have a higher final speed, and vice versa.
Which ball gets to the ground first?
As gravity is the only force in both cases, both balls will hit the ground at the same time. When you throw a ball, we are assuming that you are throwing it horizontally. This means you are giving the ball only horizontal velocity.
What is a balls speed at its highest point?
At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero.
What are the velocity and acceleration of the ball at the highest point in its path?
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth (see figure 1).
Does a ball go faster up or down?
The answer is: Down. Only if there was no air resistance would the up and down times be the same.
Which bowling ball will fall faster?
The laws of gravity dictate that a bowling ball will always drop faster than a feather. But try the same experiment in a giant vacuum and that’s when it gets interesting.
What falls faster a feather or a bowling ball?
The feather-bowling ball duo doesn’t fall at a slower rate because the feather is lighter than just the bowling ball alone — instead, they both fall at exactly the same rate.
Does heavier object fall faster?
Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.
How long does the ball take to hit the ground after it reaches its highest point?
approximately 1.84 s
The time it takes to come down is the same as the time it takes to go up. Hence, the ball takes approximately 1.84 s to hit the ground after it reaches its highest point.
What is the velocity 1s before it reaches its highest point?
At the top, its velocity is zero. (b) What is its velocity 1 s before it reaches its highest point? One second before reaching the top, it is moving up at v = 10 m/s.
How long would it take to fall 700 feet?
According to the fall time formula, it would take 6.6 seconds to reach this speed Reformulating the velocity formula, the total free-fall distance required to reach this velocity is over 214 meters (700 feet).
How long would it take to fall 200 feet?
On average, it takes one second to fall 200 feet. That said, it does take a bit of time to accelerate up to what’s called your ‘terminal velocity’. This is the fastest speed you’ll fall at during your jump. It’s typically around 120mph.
How fast does a person fall from the sky?
In a stable, belly to earth position, terminal velocity of the human body is about 200 km/h (about 120 mph). A stable, freefly, head down position has a terminal speed of around 240-290 km/h (around 150-180 mph).
What is the velocity of an object when it hits the ground?
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
What is the acceleration of the ball at the moment the ball has zero velocity?
Also, at the moment the ball has zero velocity =g=10m/s2.
Why does the speed of a ball thrown upward decrease as it goes higher?
The speed of a ball decreases as it goes upward because the force of gravity always acts downwards. When the ball is thrown upward it is moving against the gravitational force as a result the force of gravity acts upon it hence pulling it downwards whereas the ball continues its motion upwards until a certain time.
Why does a ball take longer to go down than up?
While coming down, the force of air drag is upward and the force of gravity is downward, so the ball’s downward acceleration has average magnitude less than g, say adown < g. . As aup > adown, so tdown > tup , thus it takes longer coming down.
When we throw a ball upward what happens to its speed?
When we throw a ball upwards, its speed retards gradually. This is because the earth produces a gravitational force which brings down everything that goes up. So when a ball is thrown upward the gravity applies force to bring it down which decreases its speed of going up.
What falls faster bowling ball or marble?
For example, if you ask someone what would fall faster, a bowling ball or a marble, I bet a lot of folks would say the heavier bowling ball falls faster. But in fact, if dropped from a meter or so off the ground, they’d fall at the same rate. Gravity accelerates them at the same rate, so they fall at the same rate.
Which hits the ground first a golf ball or a bowling ball?
at the same time
Answer? They hit at the same time.
Does mass affect speed?
Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.
