Question

o) A 1200 (kg) car has an initial speed of 27.0 () while moving over level ground. During its motion the car has a net force in the tangential direction of F 4250-3.6 v (N e of 45.0° before the curvature changes to the opposite direction, with the same radius. The car is ap proaching a hill 160 (m) away. The hill has a radius of 150 (m), and spans an 150 (m) 45.0 27.0 160 (m) Draw a FBD for the car in the n-t coordinate system once it has travelled 200 meters rom the cars starting position Note: show all forces, and keep in mind the driver produces a variable propelling force such that the above equation for the net force in the tangential direction is valid for the entire motion. [3 points) a. Find the normal force between the car and the road once the car has travelled the 200 meters to its final position using Newton's 2nd law in the n-t co-ordinate system. points b.
