Question

 A body of mass 50 kg moves with a velocity of 10 m/s. Find out the kinetic energy of the body?​

Answer 1

Explanation:

Given, Mass m = 50 kg Velocity = 50 cms-1 1 cm = 0.01 m So, velocity = 50 ×0.01 ms-1 v = 0.5 ms-1 We know, Kinetic energy = 1212mv2 Substituting value of m and v in the equation: Kinetic energy = 1212 × 50 × 0.52 = 1212 × 12.5 kgm2s-2 = 6 JRead more on Sarthaks.com - https://www.sarthaks.com/943606/calculate-the-kinetic-energy-of-a-body-of-mass-50-kg-moving-with-a-velocity-of-50-cm
