Question

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

Answer 1

K.E=1/2×m×v^2
=1/2×15×4^2
=1/2×15×16
=120J

➧ Mass = 15 Kg
➧ Velocity = 4 mˢ−1

❱ Kinetic Energy ➾ 1 / 2 mv²
              ➾ 1/2 × 15 × (4)²
              ➾ 120 J ...✔
