Question

2 cars A and B of masses m and M accelerate from rest in linear direction. The mass of B is twice that of A. The acceleration due to car is 1m/s2.after a time t seconds it is noticed that the kinetic energy of A is twice that of B. calculate the accelerator produced by the car B.

Answer 1

this is the ans you need
when I equate mv2 and 1/2 mt2 then 2 is multiplied with mv2
then the answer will be 2
and that is correct
