A suspended platform of negligible mass is connected to the floor below by a long vertical spring of force constant k = 1200 N/m. A circus performer of mass m = 70 kg falls from rest onto the platform from a height of h = 5.8 m above it, as shown below. Initially, the spring is not compressed or stretched. For this problem, define your system to consist of the person, platform, spring, and Earth, and you should take the reference point y = 0 to be the initial height of the platform. Part (a) Determine the total mechanical energy for this system. Is it conserved? Defend your reasoning. Part (b) As the performer falls, consider the following two segments of their descent: (i) from the moment the performer starts moving until they reach the platform, and (ii) from the moment they start compressing the platform until they reach a maximum compression. For each of two segments, describe what happens to the kinetic energy, gravitational potential energy, and spring potential energy in the system. You should be specific about what forms of energy are present and how they are being converted from one to another.

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v→0 = 17.5 m/s. The cliff is h = 38.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? x0 = m y0 = m (b) What are the components of the initial velocity? v0x = m/s v0y = m/s (c) Write the equations for the x-and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) vx = vy = (d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x = y = (e) How long after being released does the stone strike the beach below the cliff? s (f) With what speed and angle of impact does the stone land? v→f = m/s θ = ∘ below the horizontal

A block of mass m is released from rest and slides down a frictionless track of height h as is shown. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring of force constant k. Determine an expression for the maximum distance the spring is compressed. NOTE: Express your answer in terms of m, h, k and any other relevant physical constants.
