Question

A 50 kg cheetah has 3,600 J of kinetic energy. What is its velocity? m/s

Answer 1

Ke=.5MV^2
3600=.5(50 kg) v^2

Sqrt(3600/.5(50kg))=v

Velocity = 12 m/s

Answer 2

Velocity of cheetah will be = 12m/s

What is kinetic energy ?

Kinetic energy is a form of energy that an object or a particle has by reason of its motion or energy which a body possesses by virtue of being in motion.

given

mass = 50 kg

kinetic energy = 3600 J

Kinetic energy = 1/2 m v^2

        3600       = 1/2 * (50) * v^2

        v^2 = 3600 * 2 / 50

        v^2 = 144

         v = 12 m/s

Velocity of cheetah will be = 12m/s
