What will the speed of the mass be when it has moved a total distance of 1.0 m up the incline from its starting position.

Consider a disc of mass M with a radius of 0.5 m that is lying on a slope at a 45-degree angle to the horizontal. It grips the hill well and does not slide. The disc is designed in such a way that its mass per unit area, (r), equals r1/2 kg m2, where r is the disc's radial distance in metres from its axis. Calculate the disk's mass.

Consider the mass-on-a-spring system as shown in the figure below. The spring has a spring constant of 1.86e+3 N/m, and the block has a mass of 1.39 kg. There is a constant force of kinetic friction between the mass and the floor of 4.71 N. Starting with the spring compressed by 0.117 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at the spring's equilibrium position, marked x=0 in the figure. Give your answer as the distance from the equilibrium position to the final position of the block.) Hint: How much work must friction do in order to bring the mass to a stop? How much distance is required for friction to do this work? Enter answer here www.m X = 0 Please enter a numerical answer below.
