Question

An object is protected upward with a velocity of 100 m/s after what time it be astract the ground.. use=. g= 10 m/s
​

Answer 1

The Earth's gravity accelerates downward at 9.8 m/s^2. After 100/9.8 or 10.2 seconds, the ball will top out and come to a halt. It will take the same amount of time to fall to the ground, so the answer is 20.4 seconds.
