A ball is thrown vertically upward. It has a speed of 10 m/sec when it has reached one half of its maximum height. How high does the ball rise?
Take g = 10 m/s².
-
- 10 m
- 5 m
- 15 m
- 20 m
Correct Option: A
For part AB
From 3rd equation of motion
v² = u² – 2gH 
0 = u² – 2g(H/2) = u² – gH
| H = | = | = 10 m | ||
| g | 10 |
