A hot wheels car with mass M travels at constant speed on the inside of a track that is a vertical circle with radius R = 1.37 m. The normal force exerted by the track on the car when it is at the bottom of the track, at Point A, is FN = 3.33 * FG Or FN =3.33 * M*g How much time does it take for the car to complete one revolution around the circle? Reminder: The circumference of a circle is 2n R.

A student of mass M = 98 kg takes a ride in a frictionless loop-the-loop at an amusement park. The radius of the loop-the-loop is R = 24 m. The normal force by the track on the student at the top of the loop-the-loop is N₁ = 944 N. Find the speed of M at the top of the loop-the-loop. m/s Determine the normal force on M by the track at the bottom of the loop-the-loop, assuming the speed at the bottom is the same as at the top. N

A 40 kg person is sitting on a bathroom scale while riding on a Ferris Wheel. The person's speed is 6 m/s. The scale reads 300 N when the person is at the top of the motion. Find the radius of the Ferris Wheel.

Use formulas from a page provided here No 4,5,6 please step by step No 4 4. A car goes around a curve and then around another curve. It experiences a centripetal force F1 going around the curve with radius 2R at a speed v. It then experiences a centripetal force F2 going around the second curve with radius 6R at a speed 3v. What is the ratio of the centripetal forces, F1/F2? a. 0.33 b. 0.75

In an amusement park ride, a child stands against the wall of a cylindrical room that is then made to rotate. The floor drops downward and the child remains pinned against the wall. If the radius of the room is 2.15 m and the relevant coefficient of friction between the child and the wall is 0.600, with what minimum speed is the child moving if he is to remain pinned against the wall? 07.26 m/s O3.93 m/s O 12.1 m/s 5.93 m/s 9.80 m/s
