(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 1400 kg block of granite is pulled up an incline that has an angle of inclination θ = 29 ° with a constant speed of 1.13 m/s by a steam winch (see Figure). The coefficient of kinetic friction between the block and the incline is 0.12. How much power must be supplied by the winch?

2. Relevant equations

T= uW/cos(theta)+u*sin(theta)

P=Fv

3. The attempt at a solution

T= .12(1400*9.8)/cos(29)+.12*sin(29)

T= 1765.0 N

P= FV

P= 1765*1.13

P= 1994.5 W
