Question

At a constant velocity, a 5kg bag of cement is pulled straight up a 7m wall. How much work is done by the puller? (Gravitational pull is 9.8m/s2, W(J)=F(N)*D(m)

How do I work this problem??

Answer 1

5 * 9.81 * 7 Joules

Answer 2

343 j

Answer 3

thank u for your solution

Answer 4

work = force * distance (w= f * d)
w= (7*9.8)5
343j
since work is measured in joule (J)

Answer 5

How do you solve this. At a constant velocity, a 5kg bag of cement is pulled straight up a 7m wall. How much work is done by the puller? (Gravitational pull is 9.8m/s2, W(J)=F(N)*D(m). I need to see the work done to get the answer.
