A 1.5kg object is held 1.2m above a spring with force constant 320N/m. The object is dropped on the spring how far does the object compress the spring?
Alright so what i did was mgh=0.5kx^2 but the answer is different from the book. I guess is when the object touches the spring, its exerting a force downward to the spring due to gravity so i tried mg(h+x)=0.5kx^2 and solve the equation however this is wrong again...Can someone tell me what's wrong?
