A 2.00Kg puck on a frictionless horizontal surface on the Earth is constrained to a circular orbit by a 4.00 meter long string attached to a vertical rod. Assume the string is attached to the rod by a ring that lets it revolve around the rod without friction. The string can withstand up to a 50.0N tension without breaking. If the puck is 0.750Kg, what is the maximum centripetal acceleration the string can withstand? a. 33.2 m/s2 b. 45.0 m/s2 c. 37.5 m/s2 d. 33.3 m/s2 e. 66.7 m/s2 f. 66.6 m/s2
What is the maximum speed (in m/s) that a car with a mass of 370 kg can have at point B in order for its weight to hold it to the track? (Hint: treat the car's motion at point B like uniform circular motion; the weight of the car is providing the centripetal force. How fast can the car go while remaining in its circular path?)
A 15.0 g solution in a test tube is placed in a centrifuge that spins at a rate of 2.5x10^2 .What is the centripetal force exerted on the solution if the radius of the circular motion is 12.0 cm?

A child is twirling a 0.0276-kg ball on a string in a horizontal circle whose radius is 0.125 m. The ball travels once around the circle in 0.596 s. (a) Determine the centripetal force acting on the ball. (b) If the speed is doubled, by what factor does the centripetal force increase?
A pendulum consists of a 1.60 kg mass attached to a wire that makes a fixed angle of 15.0° with the vertical. The bob swings in a horizontal circle at constant speed.

A communications satellite orbits around Earth. Earth has a radius of 6380 km, and the satellite orbits 1140 km above Earth's surface. The satellite has a mass of 915 kg, and moves with a velocity of 7280 m/s. Based on this information, what is the centripetal force exerted on the satellite? 6450 N 89,900 N 14,700 N 8710 N
A nylon string is rated to withstand a force/tension of 100 N. A boy decided to play with this string to whirl a 0.8-kg object in a horizontal circle of radius 3.5 m. As the boy increases the speed of the object, up to which speed the string will remain intact? At that moment, what is the centripetal acceleration of the object? Suppose the boy decided to break the object in half (the new mass become half the original mass), and extend the string radius to 7 m using the same quality string (to withstand 100 N force). What changes will occur to the maximum circular velocity and centripetal acceleration?
The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature. What is the car's speed at the bottom of the loop? Use g = 10 N/kg. Hint: How heavy some one feels is another name for normal force. The problem therefore tells you the normal force. If you know weight and normal force, you can determine centripetal acceleration. You can substitute a value for mass if you wish.
The figure shows the path of a park ride that travels at constant speed through five circular arcs of radii Ro, 2Ro, and 3RO. 3 1 4 Rank the arcs according to the magnitude of the centripetal force on a rider traveling in the arcs, greatest first. If multiple arcs rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all arcs rank equally, rank each as '1'. Arc 1 Arc 2 Arc 3 Arc 4 Arc 5 1. Greatest 2. Second greatest 3. Third greatest 4. Fourth greatest 5. Fifth greatest
You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 10.7 m/s at the top of the incline, which is h=37.5 m above the ground. As any good engineer would, you begin your design with safety in mind. Your local government's safety regulations state that the riders' centripetal acceleration should be no more than n=1.73 g at the top of the hump and no more than N=5.45 gat the bottom of the loop. For this initial phase of your design, you decide to ignore the effects of friction and air resistance. (Figure not to scale)What is the minimum radius Rhump you can use for the semi-circular hump?What is the minimum radius Rloop you can use for the vertical loop?
