Respuesta :

The kinetic energy of the cart moving at 4.0 m/s with a mass of 3 kg is ;  24J

Given data:

mass of cart ( m ) = 3 kg

velocity of cart ( v ) = 4 m/s

Determine the kinetic energy of the cart

Applying the equation below

Kinetic energy = 1/2 mv²

                        = 1/2 * 3 * ( 4 )²

                        = 1/2 * 48  = 24 J

 

Hence we can conclude that the kinetic energy of the cart is 24 J
