2. A 0.8 kg block is attached to horizontal spring. The system is set into motion by pushing the block 15.0 cm to the left of the equilibrium position and then released. The resulting frequency of oscillation is 2.5 Hz. Determine a) the angular frequency b) the spring constant c) expressions for the displacement, velocity and acceleration as functions of time d) displacement, velocity, acceleration, kinetic energy, elastic potential energy, and restoring force at t=1.48 s
