Question
A body of mass m= 1 kg is moving along the x-axis. Its potential energy is given by the function
U(x)=2*(x^2−1)^2
Suppose the body starts with zero speed at x=1.5 m. What is its speed (in m/s) at x=0 m and at x=−1 m?
v(x=0)=
v(x=−1)=
U(x)=2*(x^2−1)^2

Find the potential energy when x = 0 or x = -1
Then using this energy then find speed using
KE = 1/2mv^2
m = 1 kg
