a box of mass 10 kg is pressed but not attached to an idealspring compressing the spring a distance of 2.5cm after it isreleased the box slides up a frictionless incline and eventuallystops at a vertical height h, the same experiment is repeated withthe same box and spring but with an initial compression of 5cm thevertical height the box reaches the second time is ______
i'm thinking its 2x because its 2x the compression but let meknow I might be very very wrong
