A 25 kg ball is thrown into the air when thrown it's going 10 m/s calculate how high it travels

On Earth, the acceleration of gravity is 9.8 m/s² downward.

So any object with only gravity acting on it gains 9.8 m/s of

downward speed every second.

If the rock starts out moving upward at 10 m/s, then it will

continue upward for only (10/9.8) = 1.02 second, before

it stops rising and starts falling.

Its average speed during that time is (1/2) (10 + 0) = 5 m/s.

At an average speed of 5 m/s for 1.02 sec,

the rock rises

(5 m/s) x (1.02 sec) = 5.102 meters.
