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.
