A spring is kept compressed by a toy cart of mass 150 g.On releasing the cart.It moves with a speed of 0.2 ms^(-1) .Calculate the potential energy (elastic)of the spring . |
|
Answer» Solution :Given ,m=150 g =`150 XX 10^(-3) kg ,v=0.2 m ^(-1)` On releasing the CART,the spring tries to COME back to its uncompressed STATE by pushing the cart away.Thus the potential energy stored in the spring changes.into the kinetic energy of the cart. Potential energy of spring U |
