Question

A ball is thrown vertically upward.
it has a speed of 10 metre per second when it is has reached one half of its maximum height. how high does the ball rise

Answer 1

Answer:

-5 is right ansr

Explanation:

we know that max height = u^2sin^ 90/2g

given u= 10 m/s

angle =90

g= -10 due to acceleration due to gravity

max height =10 ×10 ×1^2/2×-10

100 /-20=-5m ansr
