Question

A ball is thrown from the top of a building of height 25m with a sspeed of 15 m/s

Answer 1

Answer:

Therefore, it takes 2.5 seconds to reduce the upward velocity of 25 m/s to zero. After 1 second, the speed drops from 25 m/s to 15 m/s; after 2 seconds,it is down to 5 m/s; another half second is required for gravity (at -10 m/s/s) to reduce the upward velocity to zero, at the highest point.

Answer 2

Answer:

0.6

Explanation:

d= Speed/Time

d= 15/25

d= 0.6m
