1) 6 degrees per second ( you can convert it from degrees it that's not what you're looking for)
2) .47 cm per sec
If the applied force is in the same direction as the object's displacement, the work done on the object is:
W = Fd
W = work, F = force, d = displacement
Given values:
F = 45N
d = 12m
Plug in and solve for W:
W = 45(12)
W = 540J
