Hey everyone, my first post here, hope it's ok that it's a question...
I've got this physics problem that is absolutely stumping me, is abnormal from all the other forces problems I've done before, and uk is throwing me for a loop too...here it is:
6. [SFHS99 5.P.60.] A 5.5 kg block is pushed 3.1 m at a constant speed up a vertical wall by a constant force applied at an angle of 30.0° with the horizontal, as shown in Figure 5-23.
Figure 5-23
Assume that the coefficient of kinetic friction between the block and the wall is 0.30.
(a) Determine the work done by the force on the block
___________________ J
(b) Determine the work done by gravity on the block.
___________________ J
(c) Determine the normal force between the block and the wall.
___________________ N
Any help or hints you guys can give me would be greatly appreciated...this one has me stumped.
