Homework Statement
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?
Homework Equations
For part A - mgh = 1/2kx2
h = xsin28
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.
