A block of mass 3.00 kg is pressed against a spring (k=3,100N/m) near the bottom of a board inclined at θ = 28.0°

A block of mass 3.00 kg is pressed against a spring (k=3,100N/m) near the bottom of a board inclined at θ = 28.0°, as shown in Figure A2.08. When released, the block is projected up the incline and the spring expands by 14.0 cm to its normal length. Using the law of conservation of energy, determine the maximum distance (d) traveled by the block up the incline,

(a) in the absence of friction.

(b)when the coefficient of kinetic friction between the block and the board is 0.200.

    A block of mass m is pushed against an ideal spring of constant of k, compressing it over a distance x with respect to its natural length. When the block is released, it moves up a rough ramp of inclination θ and coefficient of friction μk.What is the maximum distance (d) that the block travels up the incline? You MUST use conservation of energy to solve this problem. Epress your answers in term of m, g, k, μk and θ.

    You push a 2.5 kg block against a spring, compressing the spring by 35 cm. Then you release the block, and the spring sends it sliding up the inclined plane. The spring constant is. k = 197 N/m and the coefficient of kinetic friction is, mu_k = 0.31, theta = 38 degree. How far along the incline does the block slide from the compressed position when it is released?
