A truck weighing 9000 kg is travelling down the 401 at a constant speed of 100 km/hr for 3 hours. Around London, it hits an incline of 6 degrees to the horizontal and begins to travel up the hill with an acceleration of 4.2m/s2. The friction forces on the truck add up to 6300 N.
a) Draw a neat FBD of the truck indicationg all the forces actiong on it.
b) What forces does the truck excert againts the road along the direction of travel (give magnetitude and direction)?
c) What forces does the road excert on the truck along the direction of travel (give magnitude and direction)?
d) With the truck's engine working just as hard, what would be the acceleration of the truck down the hill (again FBD is needed)?
