Question

An object of mass 50 kg moves with a speed of 10m/s. Calculate the kinetic energy of the object?

Answer 1

a 50 kg ball traveling at 20m/s 4 times more

a 50 kg ball traveling at 5m/s 4 times less

a 50 kg ball traveling at 10m/s the same

Explanation: just got it wrong on e d g e

Answer 2

mass = 50kg
velocity = 10m/s
KE = 1/2 mv^2
= 1/2 × 50 × 10^2
= 2500J
