A 2.65 kg mass oscillates back and forth on a spring with a velocity vector that varies as a function of time according to the following v(t)=(3.95cm/s) sin [0.79 rad/s]
What is the maximum speed of mass
What is the spring constant if the spring in n:m
How fast us the mass moving at t= 5.0 sec in m/s
Homework Answers
Answer question
v(t)=Vosin(wt)
Vo=V max=3.95cm/s
w=sqrt(k/m)
thus,k=w2m=1.65N/m
|v(5)|=0.0285m/s

A block is attached to a horizontal spring and oscillates back and forth on a frictionless horizontal surface at a frequency of 3.00 Hz, with an amplitude of 5.08 x 10-2m. At the point where the block has its maximum speed, it splits into two identical (equal-mass) blocks and only one of these remains attached to the spring. A. What is the amplitude and frequency of the simple harmonic motion of the piece that remains attached to the spring? B....

A classic spring/block system is moving back and forth on an air track (no friction). The mass of the block is 0.5 kg and the spring constant is 200 N/m. The mass is pulled back from equilibrium and then quickly pushed into motion such that it has an initial speed at the release point (60 cm from the equilibrium position) of 5.0 m/s. Determine the frequency of this oscillator.
