Question

two toy cars A and B of masses 100g and 200g are moving with the same speed on a smooth surface. which of the two has greater kinetic energy?​

Answer 1

Kinetic energy =

$\frac{1}{2} \: \times \: mass \times {velocity}^{2}$

Since the speed of both the cars is same, hence the car with greater mass will possess more kinetic energy.

Car B has more mass than Car A, hence the kinetic energy of car B is greater.
