Question
A 156 g object is attached to a spring and oscillates on a horizontal air track. The object is stretched
a distance 15 cm and released. The sensor measured a maximum speed of 3.84 m/s. [Answer in 3
significant figures]
What is the spring constant value?
b)
At what position(s) will the object have a speed 1/3 that of the maximum speed? Take x =
0 at the equilibrium.
c)
a)
At t= 0, the object is moving at 1/3vmax towards the equilibrium with the spring
compressed. Using (t) = A cos(wt + po), write a complete expression to describe the motion
of the object.
