Question

a) What is the mechanical energy E of the linear oscillator of Problem 1 above. (Initially, the block’s position is x = 11 cm and its speed is v = 0. Spring constant k is 65 N/m.)
b) What are the potential energy and kinetic energy of the oscillator when the block is at x = A/2? (A represents the amplitude of oscillations)

1) A block whose mass m is 680 g is fastened to a spring whose spring constant k is 65 N/m
(See figure below). The block is pulled a distance x = 11 cm from its equilibrium position
at x = 0.0 on a frictionless surface and released from rest at t = 0.0.
a) What are the angular frequency, the frequency, the amplitude, and the period of the
resulting motion?
b) What is the maximum speed of the oscillating block, and where is the block when it
occurs?
c) What is the magnitude of the maximum acceleration of the block?
d) What is the displacement function x(t) for the spring-block system?
Answer: a) angular freq =9.8 rad/s; frequency = 1.6 Hz, Period = 0.64 s
b) 1.1 m/s, c) 11 m/s? d) write it in x(t) = Acos ot format
m
frictionless
x= - A
x = 0
x = A
2) a) What is the mechanical energy E of the linear oscillator of Problem 1 above. (Initially,
the block's position is x = 11 cm and its speed is v= 0. Spring constant k is 65 N/m.)
b) What are the potential energy and kinetic energy of the oscillator when the block is at
x= A/2? (A represents the amplitude of oscillations)
Answer: a) 0.39 J b) Pot. Energy =0.098 J, Kinetic Energy = 0.30 J
