Write the word or phrase that best completes each statement or answers the question.
-A 1.5-kg cart attached to an ideal spring with a force constant (spring constant) of 20 N/m
oscillates on a horizontal, frictionless track. At time t = 0.00 s, the cart is released from rest
at position x = 10 cm from the equilibrium position.
(a) What is the frequency of the oscillations of the cart?
(b) Determine the maximum speed of the cart. Where does the maximum speed occur?
(c) Find the maximum acceleration of the mass. Where does the maximum acceleration
occur?
(d) How much total energy does this oscillating system contain?
(e) Express the displacement as a function of time using a cosine function.
