$.$ You exert a force of 476N$476N$ on a snow blower along its handle, directed at 67.0$67\mathrm{.}0$ below the horizontal, which causes the 37.0kg$37\mathrm{.}0kg$ snow blower to move at a constant speed. 

 a)$)$ What is the horizontal component of the force you exert? 

 b)$)$ What is the vertical component of the force you exert? 

 c)$)$ What frictional force is exerted on the snow blower? 

 d)$$ What is the coefficient of friction?
