A 21.00 kg mass is attached to a spring with spring constant 315.00 N/m. There is negligible friction. Initially it lies at rest at the origin. At t=0, it is given a quick and hard 'tap' from a hammer, setting it into motion. At t = 0, the position is zero: x(0) = 0 and the speed is 3.33 m/s: v(0) = -3.33 m/s. include + or - as needed 500000 3.33 m/s Equilibrium, x=0 +x 0. determine the equation of motion (this requires finding A and c) 1. What is the position at t = 3.00 s? 2. What is its velocity (speed and direction) at 3.00 s? 3. What acceleration and force does it have at t = 3.00 s? 4. What is the energy in this system at t = 3.00 s? 5. What is the kinetic energy of the system at t = 3.00 s? 6. What is the potential energy of the system at t = 3.00 s?
