Homework Statement
A 1.4-kg cart is attached to a horizontal spring for which the spring constant is 60 N/m . The system is set in motion when the cart is 0.27m from its equilibrium position, and the initial velocity is 2.6 m/s directed away from the equilibrium position.
A. What is the amplitude of the oscillation?
B. What is the speed of the cart at its equilibrium position?
Homework Equations
E=K+U
The Attempt at a Solution
U=½kΔx2 =½⋅60⋅0.272=2.187J
K=½mv2=½⋅1.4⋅2.62=4.732J
E=K+U=½mvf2
Is this the right way to proceed?
