A 2-kg block is initially at rest on a horizontal


A 2-kg block is initially at rest on a horizontal frictionless surface at x = O. A horizontal force of F = (2.5 - x2) i is applied to the block, where F is in N, and x is in meters.

(a) What is the kinetic energy of the block as it passes though x = 2 m?

(b) What is the maximum kinetic energy of the block between x = 0 and x = 2 m?
