Sagot :
The work W done on the barrel by the force of gravity is 1,461.86 Joules
Work done by an object
The formula for calculating the work done is expressed as:
W = Fd sin theta
where
- F is the force applied = 500 N
- d is the perpendicular distance = 10m
- theta = 17 degrees
Substitute the given parameters into the formula to have:
W = 500(10)sin17
W = 5000sin17
W = 1,461.86 Joules
Hence the work W done on the barrel by the force of gravity is 1,461.86 Joules
