Question

A soccer ball is kicked horizontally from the roof of a building 150m tall and lands about 200m from the base of the building. Calculate the initial speed of the ball.

Answer 1

Answer:

200/root30

Explanation:

H=150m

R=200m

$r = ut$

$t = \sqrt{2h \div g}$

$t = \sqrt{30}$

$u = r \div t$

u=200/root30
