Question

two toy cars A and B masses 200 and 500 gram respectively are moving with the same speed. Which of the two has greater kinetic energy ?​

Answer 1

Answer:

kinetic energy of car B is greater

Explanation:

KE= (m×v×v)/2

where v is speed of car

then

K.E of car A is=(200×v×v)/2=100v×v

K.E of car B=(500×v×v)/2=250×v×v

K.E of B car is greater
