A 4.0-Kg particle is moving with a velocity 20.0 m/s in the +xdirection when it is at position x=1.0 For x>1.0 m, the particle experiences a single force F= (α-βx)i, where α=36.0N and β=52.0 N/m. Determine
A) the work done by the force on the particle as it moves from x=1.0m to x=5.0m.B) the velocity of the particle at x=5.0 m.C) the position along the +x axis where the velocity of the particle equals zero.
