A body is moved through a distance of 500m by a force of 20N. If the power developed is 0.40Kw. Calculate the time for which the force acts? Physics 1 Answer CrispyRounds Aug 5, 2018 #t=25s# Explanation: First solve for work done with the formula #W=Fd# #W=20N*500m=10000J# Use power formula to solve for time, using #P=W/t# #400W=10000J/t# converted to watts instead of Kw since Joules per second is equal to watts #t=25s# Answer link Related questions How do I determine the molecular shape of a molecule?
