Math Assignment

A horizontal force of 80N acts on a mass of 6Kg resting on a horizontal surface. The mass is initially at rest and covers a distance of 5m in 0.92s under the action of the force. Assuming there are no energy losses due to air resistance and therefore that the acceleration is constant

a) calculate the total energy expended in the acceleration
b) calculate the coefficient of friction between the mass and the surface.

c) Plot a graph of the Kinetic energy of the mass against time

d) plot a graph of the kinetic energy of the mass against distance Calculate the coefficient of friction between the mass and the surface
