Question

Calculate the kinetic energy of a car of mass 500kg moving with a velocity of
36km/h. Find the kinetic energy if the velocity of car doubles? aba ​

Answer 1

Answer:

Explanation:

kinetic energy=1/2mv²

                     =1/2*500*(36)²

                     =324000J

after velocity is doubled=1/2*m*v²*v²

                                        = 1/2*500*1296*1296

                                       =419904000J
