calculate the kinetic energy of a car of mass 750 kg moving with a velocity of 72km/hr.find the kinetic energy if the velocity of the car becomes three times
Open in App
Solution
Given mass, m = 750 kg
v = 72 km/hr
use the formula :
K.E. = 1/2 mv2
Substitute the values in the above given formula to get your answer.
For the IInd case:
take v = 72 X 3 = 216 km/hr and proceed the same method as explained above.
