A force given by F(x) = 2x3 (in N/m3) acts on a 1-kg mass moving on a frictionless surface. The mass moves from x = 1 m to x = 5 m. Assume all motion is along a straight line. (a) How much work is done by the force? (b) If the mass has a speed of 1.0 m/s at x = 1 m, what is its speed at x = 5.0 m?
The force field F (x, y) = (x + 4y)i + (x^2 − 3)j acts on an object traveling from (0, 0) to (0, 1). The object moves along the path x = c(y − y^2 ) with 0 ≤ y ≤ 1.
