Question

A car and a truck are moving with same velocity of 60km/h ? Which one has more kinetic energy

Answer 1

mass of car = m
mass of truck =M M>>>m
kinetic energy =1/2MVsquare
velocity is same

truck kinetic energy is more than car

Answer 2

K.E = 1/2 mv^2

Velocity of both is same as 60 km/he

Truck has a higher mass and as K.E depends on both mass and velocity, thus, truck will have a higher K.E than the car which is lighter in mass.
