A 4 kg block is compressing a spring (k=555N/m) by 0.2m. The block stays in place until someone takes their hand away from the block. The block then slides on the frictionless ground for 2m and then slides up a 30degree ramp and hits another block (2kg) that is 0.5m up the ramp (diagonally). The 2kg block gains a speed of 0.6m/s up the incline right after the collision. Determine the velocity of the 2kg before the collision.

    a block with mass 0.7 kg is forced against a horizontal spring, compressing the spring a distance of 0.2m. The spring constant k is 125 N/m. When released, the block moves on a horizontal tabletop for 0.5m and then up a ramp. The coefficient of kinetic friction between the tabletop and block is 0.3, but the ramp is frictionless. To what vertical height does the block go? show work please

    •A 7.8 kg block slides down a rough incline. The friction experienced by this block is equal to 15 N. The block starts off 3 m above the ground and slides 5 m down this rough ramp until getting to a frictionless plane. This plane is 4 m long. The block then hits a spring, compressing it. The spring constant is 9100 N/m. How much is the spring compressed?

    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.
