Question

a player kicks the ball of mass 0.5kg placed at center of a field the ball leaves his foot with speed 8m/s. Calculate the kinetic energy of ball​

Answer 1

step by step explanation

change in kinatic energy

initial energy = 0

find kinatic energy = 1/2×m×v^2

here m = 0.25 kg

v= 8m/s

so kinatic energy= 1/2×0.25×8= 8

so the answer is 8 joule
