A point P in simple harmonic motion has a period of 3 sec- onds and an amplitude of 5 centimeters. Express the motion of P by means of an equation of the form d = a cos wt.

The equation of motion of a particle in simple harmonic motion is given by :x(t) =0,2cos(wt), where x is in meter and t is in seconds. At x=0,the particle's velocity is v=-1,256 m/s. The period of oscillation, t, equals?

A mass weighing 2lb stretches a spring 6in. If the mass is pulled down an additional 3in and then released, and if there is no air resistance, find the natural frequency, period and amplitude of the motion. O Natural frequency w = 8 rad/sec, Period T = sec, Amplitude R ft Natural frequency w = = 4 rad/sec, Period T = sec, Amplitude R ft O Natural frequency w = 8 rad/sec, Period T = sec, Amplitude R = ft 1 O Natural frequency w = 8 rad/sec, Period T = sec, Amplitude R = ft 8

A mass on a spring is held at a distance of 0.05 m from the equalibrium position. It is then released at time t=0 and undergoes simple harmonic motion. If the mass was 0.2 kg and the spring constant k was 6 Nm-1, what is the velocity of the mass at time = 7 seconds?
