A pair of horses uses 350 N to pull a wagon 100 m in 20 seconds. How much work is done, and how much power is used? Physics Work and Energy Work 1 Answer Michael Nov 18, 2015 Answer: #(a).# Work = #35"kJ"# #(b).# Power = #1.75"kW"# Explanation: Work done = force x distance moved in direction of force: #W=350xx100=35000"J"=35"kJ"# Power is the rate of doing work: Power in Watts = work done / time taken: #P=35000/20=1750"W"=1.75"kW"# Related questions What is a force?
