A1.2 kg block sliding on a horizontal frictionless surface is attached to a horizontal spring with k =480 n/m. let x be the displacement of the block from the position at which the spring is upstretched. at t = 0 the block passes through x = 0 with a speed of 5.2 m/s in the positive xdirection. what are the (a) frequency and (b) amplitude of the block’s motion? (c) write an expression for x as a function of time

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
