Question

A 1225 kgkg car and a 2150 kgkg pickup truck approach a curve on a highway that has a radius of 265 mm.

a. As the car round the curve at 65.0 mi/hmi/h , find the normal force on the car due to the highway surface.

b. As the car round the curve at 65.0 mi/hmi/h , find the normal force on the car due to the highway surface.

Answer 1

The car is of mass Mc = 1225 kg and the truck is of Mt= 2150 kg and the radius of the track is r = 265 mm = 0.265 m

a) The velocity of the car Vc = 65.0 mi /h or 29.05 m/s , mass = 1225 kg

hence the normal force is the centripetal force

putting the value we get F = 3.9 X 10 6 N

b) The velocity of the truck Vc = 65.0 mi /h or 29.05 m/s , mass = 2150 kg

hence the normal force is the centripetal force

putting the value we get F = 6.85 X 10 6 N
