A 0.28-kg blоck оn а hоrizontаl frictionless surfаce is attached to an ideal massless spring whose spring constant is The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. a. Determine the SHM position, velocity, and acceleration equations for this mass-spring system. (Write the equations on your submitted work and box the equations) b. Find the first time t1 at which the mass is as x = -0.052 m. t1 = s c. Determine the velocity and acceleration of the mass when it is at x = -0.052 m. v = m/s a = m/s2
