Q1Energy, Work and PowerFree sample

A particle of mass $8\text{ kg}$ is pulled at a constant speed a distance of $20\text{ m}$ up a rough plane inclined at an angle of $30^{\circ}$ to the horizontal by a force acting along a line of greatest slope.

(i)

Find the change in gravitational potential energy of the particle.

(ii)

The total work done against gravity and friction is $1146\text{ J}$ . Find the frictional force acting on the particle.
