A UPS worker places a 5.00 kg package at the top of a smoothramp 2.60 m above the horizontal and gives the package an initialvelocity of 4.25 m/s as it slides down the ramp. After it reachesto the bottom of the packaging ramp, the box slides across a smoothfloor until it compresses a spring with a stiffness of 3830N/m.
a) How much will the spring be compressed before the block comesto a stop?
b) If the spring can do work at a rate of 385 W, how long willit take for the spring to be compressed by the package?
