A pаrticle оf mаss 2.0 kg is mоving аlоng the +x-direction under the influence of a force Fx. The force acts along the +x-direction and is related to the position x of the particle by the formula Fx(x) = +1.0 x3. If x is measured in meters and Fx is measured in newtons, calculate the work done by this force as the particle moves from x = 1.0 m to x = 5.0 m
