An astronaut wants to find out his mass while in orbit, to findout if he is staying healthy while in space. Since he can't use abathroom scale (why not?), he attaches himself to a spring(k=2500 N/m), pulls himself back from the spring's equil length by5 m, and times one oscillation to take 1 s.
a.) What is the mass of the astronaut?
________ kg
b.) Find the potential energy stored in the springwhen it is furthest from its equilibrium length.
____________J
c.) Find the speed of the astronaut when he passesthrough the spring's equilibrium.
____________m/s
d.) If he started at a displacement fromequilibrium of 6 m instead, how long would one oscillation takenow?
____________s
