Calculate how much work is done by the force

Reference no: EM13516282

A force given by F(x) = 5x3 (in N/m3) acts on a 1-kg mass moving on a frictionless surface. The mass moves from x = 3.87 m to x = 6.09 m.

a) How much work is done by the force?

b) If the mass has a speed of 2 m/s at x = 3.87 m, what is its speed at x = 6.09 m?
