Science: How do I figure out this equation? I need to know this type of stuff for my GED test.?
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)
Here are the possible answers:
A. 343 m/s2
B. 343 N
C. 340 J
D. 343 J
I think 9.8m/s2 is actually 9.8m/s (squared) and Answer A: 343 m/s2 is 343 ms (squared). Sorry, it went that like the original at first because I copied and pasted.
