1. The problem statement, all variables and given/known data
A 1200 kg block of granite is pulled up an incline that has an angle of inclination q = 23 ° with a constant speed of 1.23 m/s by a steam winch (see Figure). The coefficient of kinetic friction between the block and the incline is 0.14. How much power must be supplied by the winch?

2. Relevant equations

(That I know of) P=TxV

3. The attempt at a solution
I need help finding the tension in the cable between the winch and block. Thanks in advance!

Welcome to PF.

Draw a force diagram. What forces are there? What forces are there along the line of the Tension in the cable that needs to be overcome?

Forces in the X direction are friction and weight (MG) and of course T which we need to find. I', just stuck on how to use these.

OK. Write a force equation. What must be balanced if it is not accelerating, but moving at constant speed?

The force of friction and mg and the pulling force.
