Question

Two blocks are placed on a frictionless ramp and held against a spring that is compressed 50cm. (The mass of the block in Case A is 1kg, the mass of the block in Case B is 5kg, the spring constant for both Cases in 250N/m) The blocks are then released from rest, and the compressed spring causes the blocks to accelerate up the ramp while in contact while in contact with the blocks. The blocks are just about to lose contact with the end of the spring. Is the height that the block travels up the ramp greater in Case A, greater in Case B, or the same in both Cases? Explain.

Explanation / Answer

see here the initial energy by compression would be same for each for mass m1=1kg the height gain would be more as compare to height attained by m2=5kg because the final energy would be Mgh so m1gh1=kx^2/2 m2gh2=kx^2/2 in both case x would be same and here u can see that h1>h2
