Ablock with a mass of 0.600 kg is connected to a spring, displaced in the positive direction a distance of 50.0 cm from equilibrium, and released from rest at t = 0. the block then oscillates without friction on a horizontal surface. after being released, the first time the block is a distance of 35.0 cm from equilibrium is at t = 0.200 s.(a) what is the block's period of oscillation? (b) what is the the value of the spring constant? (c) what is the block's velocity at t = 0.200 s? (indicate the direction with the sign of your answer.(d) what is the block's acceleration at t = 0.200 s? (indicate the direction with the sign of your answer.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
