One end of a spring of constant k =100 N/m is attached to a wall.To the other end is attached a mass, m = 2.1 kg. The mass isdisplaced 0.15 m from equilibrium and released from rest at t = 0s.
a) Find the period of simple harmonic motion for themass.
b) find the angular frequency of simple harmonic motion for themass.
c) find the maximum and maximum speeds of the mass in thecourse of its motion.
d) find the maximum and minimum acceleration of themass.
e) at time t= 1s, find the position, velocity, and accelerationof the mass.
