Question 12

Q12) Two toy-car A and B of masses 500g and 200g respectively are moving at the same speed. Which of the two has the greater kinetic energy?

  • Solution

  • Transcript

Solution :

The toy car ‘A’ of mass ‘500 gm’ has greater kinetic energy.

K.E. =\frac{1}{2}Mv^2

Both the cars are moving at the same speed, so the car with greater mass will possess greater kinetic energy.

"Hello, welcome to Lido home back. Today. We are going to see two toy courses A and B of mass are fine and terms and who are conscious particularly moving at the same speed which of the following are creators kinetic energy. So we know that kinetic energy is going to be half MV square of Yuppie with so let's look here. Both of the cars are moving at the same speed. So the car with the greater mass will possess greater kinetic energy. That bit Massachusetts content is fighting and interactive of Mission to Mars. So which has more masks are a toy car that has more mass and more kinetic or kinetic energy. I hope you understood this Video subscription sharp regular updates. Thanks for watching this video."
