Asingle conservative force acts on a 5.30-kg particle within a system due to its interaction with the rest of the system. the equation
fx = 2x + 4
describes the force, where fx is in newtons and x is in meters. as the particle moves along the x axis from x = 1.08 m to x = 6.50 m, calculate the following.
(a) the work done by this force on the particle
1 j
(b) the change in the potential energy of the system
2 j
(c) the kinetic energy the particle has at x = 6.50 m if its speed is 3.00 m/s at x = 1.08 m
3 j
