A 020-kg particle moves along the x axis under the, Ask an Expert

Academics

A 0.20-kg particle moves along the x axis under the influence of a conservative force. The potential energy is given by U(x) = (8.0 J/m2)x2 + (2.0 J/m4)x4,

where x is in coordinate of the particle. If the particle has a speed of 5.0 m/s when it is at x = 1.0 m, its speed when it is at the origin is:

a) 0 m/s

b) 2.5 m/s

c) 5.7 m/s

d) 7.9 m/s

e) 11 m/s
