A ball is thrown vertically upwards from the ground with an initial velocity of 50ms-1. What is the total time spent by the ball in the air? (g = 10ms-2)
- 2.5s
- 5.0s
-
10.0s
- 15.0s
- 20.0s
The correct answer is: C
Explanation
Time to move up:V = U - gt
0 = 50 - 10t
t = 5.
Total time spent on air = 2t = 10.0s
