A racing bicycle with rider has a combined mass of 85 kg. The racer is on a velodrome (circular racing track) that has banked curves. The surface is banked at an angle of 35° from horizontal. The track has a radius of 60 m. a) Draw a free-body diagram of the racer viewing the racecar from the front (left) and from above (right.) Ignore friction. Indicate the direction of the acceleration of the racer next to your diagram.

A child of mass 40.0 kg is in a roller coaster car that travels in a loop of radius 9.00 m. At point A the speed of the car is 11.6 m/s, and at point B, the speed is 12.6 m/s. Assume the child is not holding on and does not wear a seat belt. B A 30° (a) What is the force (in N) of the car seat on the child at point A? (Enter the magnitude.) 205.6 ✓N (b) What is the force (in N) of the car seat on the child at point B? (Enter the magnitude.) XN 109.8 (c) What minimum speed (in m/s) is required to keep the child in his seat at point A? 9.40 m/s

U3 - CIRCULAR MOTION AND ORBITS PROBLEM SET 3. A car of massm = 1300 kg traveling at 55.0 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. Use g = - 9.80 m/s? throughout this problem. What is the radius r of the turn if e = 20.0° (assuming the car continues in uniform circular motion around the turn)?

A 1600kg car moving on a flat, horizontal road negotiates a curve . If the radius of the curve is 40m and the coefficient of static friction between the tires and dry pavement is 0.65. a) Draw a free body diagram for the car . b) Calculate the maximum speed the car can have and still make the turn successfully.

Below are a number of situations involving circular motion. In each case, identify the source of the force needed to keep the objects in question moving in their circular paths. Question h

At what point, as measured from the center of the earth, does the gravitational force exerted on the spacecraft by the earth balance that exerted by the moon? This point lies on a line between the centers of the earth and the moon. The distance between the earth and the moon is 3.85 × 108 m, and the mass of the earth is 81.4 times as great as that of the moon. moon m earth em
