A math professor cycles around a corner which is banked (inclined downwards towards the center of the radius of curvature). The centripetal force that causes the bike to go round a bend in the road is usually provided by friction. This road is very icy, however. Could the force required to turn the corner be provided if the friction coefficient between the bikes tires and the road goes to 0.01? Find the range of velocities required by the bike if the radius of curvature of the curve is 120 m and the road is banked at 10 degrees to the horizontal.

Banked curves are designed so that the radial component of the normal force on the car rounding
Banked curves are designed so that the radial component of the normal force on the car rounding the curve provides the centripetal force required to execute uniform clrcular motion and safely negotlate the curve. A car rounds a banked curve with banking angle θ-27.1° and radius of curvature 157 m. (a) It the coefficient of static friction between the car's tires and the road is -0.316, what is the range ot speeds for which the car can safely negotiate the turn...

QUESTION 24 A truck of mass 3000 kg moves around an unbanked corner of radius 81.2 m. If the coefficient of static friction between the truck tires and the road is 0.800, what is the maximum speed that the truck can move without slipping, in units of m/s? QUESTION 25 Find the mass of an object, in units of kilograms, if a resultant force of 11.2 N will give it an acceleration of 2.00 m/s. QUESTION 26 What is the...
