Question

A body is moving upward with a velocity of 500m/sec?. What will be the height?
(A) 12.7 km (B) 13.7 km (C) 15 km (D) 16 km​

Answer 1

Answer:

12.7 km

Explanation:  use $V^{2} - U^{2} = 2as$

Answer 2

Answer:

A)12.7km

Explanation:

Given:

Initial velocity: 500m/s

Acceleration: 9.8m/s2

Final velocity: 0m/s

Therefore,

By third equation of motion

$2as = v {}^{2} - u {}^{2}$

2×9.8×s=0-500^2

19.6s=-25000

s=-25000/19.6

s= 1275.512m

Hence 12.75km
