A block of mass m = 4 kg is attached to a spring, and undergoes simple harmonic motion with a period of T = 0.35 s. The total energy of the system is E = 2.5 J. It assumes that
there
is no air friction where the block is oscillates at maximum displacement between A and -
A
Calculate,
ka)
frequency of the motion[1]
(b) Angular frequency of the motion [1]
(c) The force constant, k of the spring [2]
(d) What is the amplitude of the motion?[2]
(e) What is the restoring force act on the system at maximum displacement. [2]​
