A banked curve has been designed so that it is safest for a vehicle going 70 mph. The topography of the land restricts the radius of the road to 300m. Assume mu(static friction) is 0.80 and mu(kinetic friction) is 0.60.
A 5512 lb vehicle travels with a speed of 60 mph on the curve.
1. Calculate the force that the road exerts on the vehicle.
2. Calculate the friction on the tires.
The Attempt at a Solution
converted all mph's given to m/s and converted weight in lbs to N.
tried to find the angle by:
I came up with 19.45 degrees. This just doesn't seem right, that's an awfully steep bank.
The rest I'm stumped about.
