A spring is compressed by a toy cart of mass 150g. On releasing the cart, it moves with a speed of `0.2 m//s`. Calculate the elastic potential energy of the spring. |
|
Answer» Correct Answer - A::C Elastic potentail energy of the spring = kinetic energy gained by the toy cart, i.e., `E_p = E_k = (1)/(2)mv^(2) = (1)/(2)(0.150).(0.2m//s)^2 = 3xx10^(-3)J` |
