Q1Energy, Work and PowerFree sample

A man pushes a wheelbarrow of mass $25\text{ kg}$ along a horizontal road with a constant force of magnitude $35\text{ N}$ at an angle of $20^{\circ}$ below the horizontal. There is a constant resistance to motion of $15\text{ N}$ . The wheelbarrow moves a distance of $12\text{ m}$ from rest.

(i)

Find the work done by the man.

(ii)

Find the speed attained by the wheelbarrow after $12\text{ m}$ .
