1. The problem statement, all variables and given/known data 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. 2. Relevant equations F=ma Centripetal acceleration=v^2/r 3. 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: v^2/r=Wsinθ 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.
