Question

A ball is thrown vertically upward from the 12 level with an initial velocity of 18 metre per second at the same

Answer 1

ask question properly yrr

If ball thrown vertically upward then

a = -g ( due to direction of g is downward )

v = 0. ( final velocity will be zero at height)

EQ. WILL BE

1• v = u + at

0 = u - gt

u = gt

2•. h = ut - 1/2 gt^2

3•. v ^2 = u ^2 - 2gh
