Please I need help and fast!!Can anyone solve the problem below?
Mass body m=0.5kg performs simple harmonious oscillation with period T. The total energy of oscillation is E=4J. At t=0 time the body has its maximum kinetic energy and moves in the positive direction, while t=T/12 is at x=0.2m position.
a.explain that the oscillation has an initial phase and calculate its value.
b. Calculate the width of the oscillation.
c. Calculate the rate of change in the body's momentum at t=T/12
d. Calculate the work of the recommended force that the body receives from time t=0 to time t=T/12
e. Calculate the rate of change in the body's kinetic energy at t=T/12
