Question

a car and a truck are moving with the same kinetic energy which one will have greater momentum?

Answer 1

2 X 42= 22X  8

IF WE REMOVE JUST ONE SQUARE FROM BOTH THE SIDES WE GET ; 2X4 = 2X 8

THAT IS 8= 16 WHICH IS NOT POSSIBE .

SO HOW DID YOU REMOVE SQUARE FROM BOTH SIDES OF : m1 *v1^2 = m2*v2^2 AND GOT THE RESULT AS

M1*V1 =M2 *V2  .

IT ACTUALLY MEANS : M1 X V1 X V1 = M2 X V2 X V2  AND SINCE WE DON'T KNOW THAT V1 = V2 WE CAN'T CUT THEM .

Answer 2

truck has more mass.so I guess it is
