Find the kinetic energy of a ball of 250...

Find the kinetic energy of a ball of 250 g mass, moving at a velocity of 40 cm/s.

Text Solution

Verified by Experts

Mass of the ball, m = 250 g = 0.25 kg
Speed of the ball, v = 40 cm/s s = 0.4 m/s
Kinetic energy,
`K.E. = (1)/(2) (0.25) xx (0.4)^(2) = 0.02J`
