Consider the same cylinders as in part 1. this time we want to make sure that both cylinders reach the bottom of their inclines at the same time and after traveling the same distance along the inclines’ hypotenuses. to achieve this, the object that was slower in part 1 now needs to start from a higher point (steeper incline). which other physical property of motion is now identical for both objects? express the starting height of the hollow cylinder hhcyl as a function of the starting height of the cylinder hcyl, i. e. hhcyl = f(hcyl).

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
