A ball is thrown straight up at 17 m/s. How fast is the ball moving when it is 6.2 m above its release point?
Here ,
let the speed is v
Using third equation of motion
v^2 - u^2 = 2 * g h
v^2 - 17^2 = -2 * 9.8 * 6.2
solving for v
v = 12.94 m/s
the speed of the ball is 12.94 m/s

A ball thrown straight up into the air is found to be moving at 7.19 m/s after falling 2.46 m below its release point. Find the ball's initial speed (in m/s).
43) A ball is thrown straight up with a speed of 36 m/s. How long does it take to retum to its starting point, assuming negligible air resistance?
A ball is thrown straight up with an initial speed of v m/s. The ball was released 1.2 m above the ground, but when it returns back down, it falls into a hole 14.2 m deep. If the ball’s speed at the bottom of the hole is 28 m/s, what was the initial speed v (in m/s) of the ball?
1. A ball is thrown straight up and passes point at a height of 40 m above its starting point in 5 s. What was its initial speed?
A ball is thrown straight up with an initial speed of 13.7 m/s. At what height above its initial position will the ball have one‑half its initial speed?
A ball is thrown straight up with an initial speed of 14.3 m/s. At what height above its initial position will the ball have one-half its initial speed? height:
A ball is thrown straight down at 1.50 m/'s from a tall tower. Two seconds (2.00 s) later a second ball is thrown straight up at 4.00 m/s. How far apart are the two balls 4.00 s after the second ball is thrown? Ignore the effects of air resistance. Example 2-9
A ball is thrown straight up in the air with an initial speed of 40 m/s. Ignore air resistance and take g - 10m/s2. What is the speed of the ball when it reach 40 m above the ground? 20 m/s 2012 m/s 2/20 m/s 3720 m/s 20/3 mis
You throw a ball straight upward. Part A Compared with its initial speed when thrown, how fast does it return to its starting point? Answer this for the case of no air resistance. The ball returns much faster than it was thrown. The ball returns slower than it was thrown. The ball returns as fast as it was thrown. Part B Answer this for the case where air resistance does affect motion. The ball returns as fast as it was...
A ball is thrown straight upward in the air at a speed of 15.0 m/s. Ignore air resistance. a) What is the maximum height the ball will reach? b) What is the speed of the ball when it reaches 5.00 m?c) How long will the ball take to reach 5.00 m above its initial position on the way up? d) How long will the ball take to reach 5,00 m above its initial position on its way down?
