Hello there!

We need to use the formula for kinetic energy.

K.E = 0.5 * mv²

M represents the mass which is 60kg

V is the velocity which represents the speed of the moving which is 2 m/s

K.E  = 0.5 * 60 * 2²

K.E =  0.5 * 60 * 4

K.E = (30)(4)

K.E = 120

Remember that the answer should always be stated in Joules (J) which is the standard unit of measurement for Kinetic Energy.

Thus,

The correct answer is option B 120j

As always, I am here to help!
