Question: 3. A block with mass = 5 kg from rest slides down a distance x on a smooth inclined surface with an angle of 40,

3. A block with mass = 5 kg from rest slides down a distance x on a smooth inclined surface with an angle of 40°, and hits a spring with a spring constant of 450 N/m. The block stops immediately after compressing the spring 0.30 m.

(a) what is the magnitude of x

(b) what is the distance between the point where the block first contacts the spring and the point where the velocity of the block is greatest
