period of oscillation 1 answer below »

A block with a mass of 0.300 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 25.0 cm from equilibrium is at t = 0.200 s. (a) What is the block's period of oscillation? s (b) What is the the value of the spring constant? N/m (c) What is the block’s velocity at t = 0.200 s? If the velocity is in the negative direction, include a minus sign. m/s (d) What is the block’s acceleration at t = 0.200 s? If the acceleration is in the negative direction, include a minus sign. m/s2
