It is well known that runners run more slowly around a curved track than a straight one. One hypothesis to explain this is that the total force from the track on a runner’s feet— the magnitude of the vector sum of the normal force (that has average value mg to counteract gravity) and the inward-directed friction force that causes the runner’s centripetal acceleration— is greater when running around a curve than on a straight track. Runners compensate for this greater force by increasing the time their feet are in contact with the ground, which slows them down. For a sprinter running at 10 m/s around a curved track of radius 20 m, how much greater (as a percentage) is the average total force on their feet compared to when they are running in a straight line?
A high-speed railway car goes around a flat, horizontal circle of radius 470 m at a constant speed. The magnitudes of the horizontal and vertical components of the force of the car on a 51.0 kg passenger are 210 N and 500 N, respectively. (a)What is the magnitude of the net force (of all the forces) on the passenger? (b) What is the speed of the car?
a person riding a Ferris wheel moves through positions at (1) the top, (2) the bottom and (3) mid height.

It is well known that runners run more slowly around a curved track than a straight one. One hypothesis to explain this is that the total force from the track on a runner's feet--the magnitude of the vector sum of the normal force (that has average value mgmg to counteract gravity) and the inward-directed friction force that causes the runner's centripetal acceleration--is greater when running around a curve than on a straight track. Runners compensate for this greater force by increasing the time their feet are in contact with the ground, which slows them down. For sprinters running at 8 m/s around a curved track of radius 16 m, how much greater (as a percentage) is the average total force on their feet compared to when they are running in a straight line?

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 circular motion and safely negotiate the curve. A car rounds a banked curve with banking angle ? = 23.2° and radius of curvature 168 m. (a) If the coefficient of static friction between the car's tires and the road is ?s = 0.393, what is the range of speeds for which the car can safely negotiate the turn without slipping? vlow=? m/s. vhigh= ? m/s b)What is the minimum value of ?s for which the car's minimum safe speed is zero? Note that friction points up the incline here.
