Question

a body is thrown vertically upwards and rises to a height of 10m find the velocity with which the body was thrown upward (g = 9.8 metre. per second square)​

Answer 1

Answer:

sorry mate I don't know this answer but I will try to solve for you ❤

Answer 2

Explanation:

Maximum height  h=10 m/s

At maximum height,   v=0

Let the initial velocity be u.

Acceleration   a=−g=−9.8 m/s2

∴  0−u2=2(−9.8)(h)

⟹ u=2gh=2×9.8×10=14 m/s
