Answer:
Anne is pushing a wheelbarrow. work done by Anne is 1124.87 Joules.
Solution:
Given that Anne is pushing a wheel barrow filled with mulch to place in her garden. She is pushing the wheel barrow with a force of 70 N at an angle of [tex]50^{\circ}[/tex] with the horizontal.
She pushes the wheel barrow 25 meters.
Need to calculate work done.
Work done = force in the direction of moment x distance covered
So force in the direction of moment is force in the distance of horizontal that is 70cos50 newton
[tex]\text { Work done }=70 \cos 50 \times 25 \text { meters }=70 \times 0.6427 \times 25[/tex]
Work done = 1124.87 Joules.
Hence word done by Anne is 1124.87 Joules.
