Question:
A block of 0.5kg is pulled up an inclined plane by a tensile force at a constant velocity of 2m/s. Said block is pulled 15m up the incline. Sin(theta) = 1/3. The coefficient of kinetic direction is 0.08. Calculate the work done on the bock. Also, calculate the power applied to the block.
Relevant equations:
F=ma.
F(friction) = coefficient of kinetic friction x Reaction force.
Attempt at solution:
I'm not sure if I'm looking at this correctly but it seems to me that the net force will be 0. If it's pulled up at constant velocity then the net force is 0 and thus the net power and work is also 0. Is this correct?
