Question

A boy of mass 50.0 kg runs with a speed of 3.00 m/s. His kinetic energy is equal to ???J

Answer 1

Answer:

K.E = 1/2 MV^2 = 1/2 *50KG *3^2 = 225 J

Explanation:

Answer 2

Explanation:

K.E.=1/2mv²

m= 50kg

v =3 m per s

Therefore the kinetic energy = 1/2 × 50 × 3²

=25 × 9

= 225 Joules
