i need help with this i just cant figure it out
a 17.4 kg block is dragged over a rough, horizontal surface by a constant force of 185 N acting at an angle of 32.9 degrees above the horizontal. the block is displaced 58.2 m, and the coefficient of kinetic friction is .17
the acceleration of gravity is 9.8 m/s^2
find the work done by the 185 N force. answer in units of J (joules)
find magnitude of the work done by the force of friction, answer in J
work done by the normal force? answer in J
net work done on block? in J
if you can help me solve it it would help or at lease give me some instruction how to with some equations
Thanks
