Evaluate the work done by the force

Reference no: EM13334797

a 1.8 kg block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction is applied on the block. the force is given by F(x) = (2.8 - x^2) N, where x is in meters and the initial position of the block is x = 0.

a) what is the work done by the force between the initial position and x = 2.0 m?

b) what is the velocity of the block as it passes through x = 2.0 m?
