1. The problem statement, all variables and given/known data Supposed the incline is frictionless for the system. The angle of inclination is 28 degrees, the spring constant is 692 N / m and the mass of the block is 4.95 kg. The block is released from rest with the spring initially unstretched. The acceleration of gravity is 9.8 m/s2. How far x does it move down the incline before coming to rest? Choosing down the incline as the positive direction, what is its acceleration at its lowest point? 2. Relevant equations For part A - mgh = 1/2kx2 h = xsin28 3. The attempt at a solution I plugged h into the equation and got: mg(xsin28) = 1/2kx2 I cannot seem to solve for x. I do not know if this equation is correct. Thanks for any help.
