Question

A single conservative force acts on a 5.00 kg particle. Theequation Fx = (2x + 4) N describesthis force, where x is in meters. As the particle movesalong the x axis from x = 2.60 m to x = 5.00 m, calculate the following. (a) the work done by this force on theparticle
1 J

(b) the change in the potential energy of the system
2 J

(c) the kinetic energy the particle has at x =5.00 m if its speed is 3.00 m/s atx = 2.60 m
3 J (a) the work done by this force on theparticle
1 J

(b) the change in the potential energy of the system
2 J

(c) the kinetic energy the particle has at x =5.00 m if its speed is 3.00 m/s atx = 2.60 m
3 J

Explanation / Answer

b) since the force is conservative, the work done by the force onthe particle is the negative equivalent of the potential energychanges on the system... -(the answer to part A)
