- A 350 g black was pressed against the spring of force constant of 1500 N/m until the block compresses the spring 8.0 cm. The spring rests at the bottom of a ramp inclined at θ=60.0° to the horizontal. By using energy considerations, determine how far up the incline the block moves from its initial position before it stops if: a) the ramp exerts no friction force on the block. b) if the coefficient of kinetic friction is 0.400.arrow_forward1.The work required to stretch a certain spring from an elongation of 4.00 cm to an elongation of 5.00 cm is 30.5 J.

The mass slips to the bottom of the incline, strikes a spring which compresses and projects the mass back up. The coefficient of friction between the mass and the incline is μ = 0.2. Using energy principles, find how far back up the incline the mass m moves before it comes to rest. 700002 k 37° E marrow_forward
