Its acceleration is always the same - the acceleration of gravity at 32 ft/sec/sec - no matter what distance it is during drop, until it hits the ground.

What is the acceleration of a ball that starts from rest and rolls down a ramp and gains speed at 25 ms in 5 seconds?
Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
How do you calculate the acceleration of a ball that starts from rest and rolls down a ramp and gains a speed of 25 ms in 5 s?
Acceleration is the speed variation at a given time. Thus you must calculate the speed variation: Final speed - Initial speed = 25m/s-0m/s=25m/s The conscious then is performed over time.. t=5s Finally, the acceleration is a=(25m/s)/5s=5m/s2
If a car takes 10 seconds to go from 0meters per second to 25 meters per second at constant acceleration what is the acceleration?
Acceleration = (change in speed) divided by (time for the change) = (25) / (10) = 2.5 meters per second2
What is the acceleration of a car that goes form 0 miles per second to 25 miles per second in 3 seconds?
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
What is a triangle of 100ft square root what is the height of a side of 25 feet?
Assume the question should read, "If a triangle has an area of 100 sq feet and the base measures 25 feet then what is the height?"Area of a triangle = 1/2base x height.100 = 1/2 x 25 x height : height = 2 x 100 ÷ 25 = 8
How much force it needed to accelerate a 25 kg bowling ball at?
(25) times (desired rate of acceleration) Newtons.
What is the acceleration of a softball if it has a mass of 0.50 and hits the catchers glove with a force of 25 newtons?
At the point of impact, since force = mass x acceleration, acceleration = 25/0.5 = 50 N/kg If the catcher exerts a force of 25 newtons against the 0.5 kg ball, then he will cause it to accelerate at the rate of 50 m/sec-squared. If he happens to exert the force in the direction opposite to the velocity of the ball ... a common occurrence for a catcher ... then the acceleration is also opposite to the velocity of the ball, and the ball slows down.
If a ball takes 11 seconds to stop if dropped from 1 foot and 25 seconds from 2 feet how many seconds if dropped from 3 feet?
39 seconds
What is the acceleration due to gravity if an object falls down from a height of 25 m?
The acceleration due to gravity remains constant throughout the fall i.e. 9.8m/s2 ( taken as 10 for calculations).
What is the acceleration of a ball that starts from rest and rolls down a ramp and gains speed at 25 ms in 5 seconds?
Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
A ball is dropped from a height of 100 cm At each bounce it raises half the height it raised with the previous bounce Find the distance covered by the ball till it comes to rest?
300cm. Ignoring the first drop, the first bounce is 50+50cm (up then down!), the second is 25+25, the third 12.5+12.5 ... and so on. If you know or accept that 1+1/2+1/4+1/8+1/16...=2 then the bounces add up to 100+50+25+12.5...=200, and then add the initial 100cm drop to make 300cm.
How high will a basketball bounce if dropped?
If we knew from what height the ball, when dropped, would reach its terminal velocity, and if we knew the percentage of rebound the ball would give, we could then be certain. I can only guess that a basketball will rebound approximately 75% of the height from which it is dropped, and if the height at which it would reach terminal velocity is maybe 300 feet, the ball would bounce back up to 225 feet. Just a guess! A basketball has an elasticity (or "bounciness") of about 56 percent.I'm not sure there's a theoretical limit. In practice, of course, there would be one: when the velocity of the ball impacting the ground is so great the ball explodes rather than bouncing. But you'd have to fire it out of some kind of basketball cannon to get it moving that fast.The official standard for ball inflation is that the ball should bounce roughly 75% of its drop height (specifically, between 49" and 54") when dropped from 6 feet. If you're referring to just the height a dropped ball could bounce and you're not throwing it down with some kind of basketball-downward-hurling machine, you could calculate the theoretical bounce height by figuring out what terminal velocity is for a basketball, calculating how high you'd have to drop it from (assuming no atmosphere) to achieve that velocity, and then multiplying by 0.75. I'm not going to do it for you, because I'm not actually all that interested in the answer, but that's how you could do it if you are.
Jules kicks a soccer ball off the ground and in the air with an initial velocity of 25 feet per second Approximately what maximum height does the soccer ball reach?

A rolling ball has an initial velocity of 5 meters per second 30 seconds later its velocity is 2 meters per second What is the acceleration of the ball?
The acceleration of the ball can be easily found using the kinematic equation if = vi + at. Where vi = initial velocity, if = final velocity, a = acceleration, and t = seconds. The acceleration is -0.1 m/s^2.
A penny is dropped into a well and it takes 5 seconds to fall what is the depth?
d=1/2 (a)(t^2) d=distance a=acceleration t=time acceleration due to gravity is 32 ft/second so d=1/2 (32)(5^2) d=16(25) d=400
