Determine the starting position of a 15 kg block in order to have it travel 8 meters up a 30 degree ramp with a constant force applied of 8N. Assume Us and Uk both equal 0.30.

Part 1: calculate acceleration of the box up the ramp then determine velocity needed at the bottom of the ramp for the box to travel up 8m with 80N force applied.

Part 2: calculate initial position of the box needed to achieve velocity at the bottom of the ramp calulate in part 1.

Part 3: Predict whether or not the box will slide down after stopping at 8m up the ramp.

Starting with a speed of 2.50 m/s, a 2.00 kg block slides across a rough horizontal surface until it collides with a spring. The spring compresses a distance of 6.00cm as the block comes momentarily to rest. The total distance traveled by the block from its starting position to the position where it comes to rest is 0.800m. If the coefficient of kinetic friction between the block and the surface is 0.100, what is the spring constant of the spring?
