A ball of weight 500 g is thrown in the air with a speed of 40 m/s. What will be its energy at maximum height?

A

200 J

B

400J

C

600J

D

800 J

Text Solution

Verified by Experts

The correct Answer is:
B
At maximum height total kinetic energy converts into potential energy.
At maximum height
`U = K = 1/2 mv^2`
Given , `m = 500 g = 0.5 kg and v = 40 m//s`
`therefore U = (0.5 xx 40 xx 40)/(2) = 400 J`
