#### Answer

a) $5.2 m/s^2$ b) $540 \ N$

#### Work Step by Step

We know that the choice of coordinate system should not change the answer that we get when we solve. Thus, when we use a horizontal/vertical coordinate system instead of sloping the the coordinate system to match the slope of the hill, we get the same answer, which is: a) $5.2 m/s^2$ b) $540 \ N$
