Question

Two toy cars P and Q of masses 100 g and 150 g respectively are moving with the same speed. Which of two cars has greater kinetic energy? Why?
​

Answer 1

Answer:

they are moving with same speed

Answer 2

Answer:

The toy car with 150g

Explanation:

Kinetic energy of a body is directly proportional to mass if velocity is constant

As velocity is constant,

the car with greater mass ,ie, car weighing 150g, will have greater kinetic energy.
