Q11.A body of mass 60 kg moving with a speed of 20 km/h.Find it's KineticEnergy.​

Answer»

Heya!!!EXPLANATION:Here is your ANSWER Given : Mass (m) = 60 kg Speed (v) = 20km/h = 50/9 m/s  = 5.55 m/s To find : Kinetic energy (K.E.) SOLUTION : K.E. = 1/2mv² K.E. = 1/2*60*(5.55)² K.E. = 30*30.8 K.E. = 924 kg m/s or Joule So, the kinetic energy of a body having mass 60 kg moving with speed of 20km/h  will be 924 Joule.#Hope it helps :D#Stay SAFE :D
