Question

An object of mass 15 kg is moving with a uniform velocity of 4 m s-1. What is the kinetic energy possessed by the object?

Answer 1

Answer:

Mass of the object, m = 15 kg Velocity of the object, v = 4 m/s Ek = 1/2mv2 = 1/2 × 15 kg × 4 ms-1 × 4 ms-1 = 120 J The kinetic energy of the object is 120 J.

Answer 2

Answer:

120

Explanation:

k.e=1/2mv^

=1/2×15×4×4

=120
