(Answered) A 15kg block is initially at rest on a horizontal

Academics

A 1.5kg block is initially at rest on a horizontal frictionless surface when a horizontal force along an xaxis is applied to the block. The force is given by F(x) = (2.5 - x^2) i N, where x is in meters and the initial position of the block is x = 0.

(a) What is the kinetic energy of the block as it passes through x = 2.0m?

(b) What is themaximum kinetic energy of the block between x = 0 and x = 2.0m?
