Question

(15) A truck with failed brakes accelerates (in the +x direction) down a slope angled at phi =8deg above the horizontal. The truck has a mass of 31,000kg, and the force labeled F_(air ) is 25,000N. Note that the truck is traveling in the +x direction in the picture. Use the labels on the free body diagram to the right. a) (2) Set up Newton's 2^(nd ) Law in the x direction using the labels on the free body diagram b) (2) Set up Newton's 2^(nd ) Law in the y direction using the labels on the free body diagram c) (3) Find the normal force N d) (2) Find the acceleration of the truck e) (2) Find the work done by the weight ( mg ) when it has traveled 500m down the hill f) (3) Find the net work done on the truck when it has traveled 500m down the hill g) (3) If the truck starts with a speed of 12(m)/(s), how fast is it going when it has traveled 500mdo hill?
