Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

100%

A car of mass M = 900 kg traveling at 60.0 km/hour
enters a banked turn covered with ice. The road is
banked at an angle 0, and there is no friction between
the road and the car's tires as shown in (Figure 1). Use g
= 9.80 m/s throughout this problem.

Part B
Now, suppose that the curve is level (0 = 0) and that the ice has melted, so that there is a coefficient of static
friction u between the road and the car's tires as shown in (Figure 2). What is Umin, the minimum value of the
coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume
that the car's speed is still 60.0 km/hour and that the radius of the curve is 77.9 m .

As shown in the figure below, a small ball (can be considered as a particle) with mass m moves in a circular motion with a constant speed V around the center O in a frictionless horizontal plane. The radius of the circular motion is R. The central acceleration force Fon the ball is provided by a rope through the center O. Now we pull the rope to reduce the radius of the circular motion to R/2. What is the speed of the ball after the radius is reduced to R/2?

A car making a turn on a dry, banked highway ramp is experiencing friction. The angle of the bank is 40 degrees and the radius of turn is 78 m, what is the coefficient of static friction between the tires and the road if a 1350 kg car safely turn at 45m/s?
A car going around an unbanked curve is found to be able to take the curve with maximum speed “v.” You would like to triple the maximum speed the car can take the curve. To do this, you could: triple the coefficient of friction between the car and the road; decrease the radius of the road by a factor of three increase the radius of the road by a factor of nine decrease the coefficient of friction between the car and the road by a factor of nine;

Engineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R = 270 m and bank angle 9, where the coefficient of static friction between tires and pavement is us. A car (without negative lift) is driven around the curve as shown in Figure (a). Find an expression for the car speed Vmax that puts the car on the verge of sliding out, in terms of R, 8, and us. Evaluate Vmax for a bank angle of 0= 11° and for (a) μ = 0.48 (dry pavement) and (b) us= 0.043 (wet or icy pavement). (Now you can see why accidents occur in highway curves when icy conditions are not obvious to drivers, who tend to drive at normal speeds.)
