A rock with a 8 kg mass is tied to a string and swung in a circular path. The 1.8 meter string is tied to a post, and during the motion, the string has a 35° angle with the post. The rock makes 100 rounds in 3 minute. The centripetal force on the ball is ___ N

sub=15

A rope with a length of 2.0 m is used to swing a 0.25 kg object in a horizontal circular motion with a uniform speed of 20.0 m/s. a) What is the force of tension in the rope? b) What is the period of rotation? (Hint: the time taken for the ball to complete one entire circle)

Ignore gravity in this problem.  A boy swings a ball on a string around his head in a circle.  Calculate the force (in Newtons) he must pull on the string with, if these are the parameters: v = 8 m/s r = 7 meters m = 8 kg

A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 3.37 m radius, if the riders is subjected to a centripetal acceleration 2.5 times that due to gravity, what is the spinning speed in unit of revolutions per minute? Use g = 9.8 m/s2.

The curved section of a speedway is a circular arc having a radius of 190 m. The curve is properly banked for racecars moving at 34 m/s. At what angle with the horizontal is the curved part of the speedway banked?

A ball of mass 4.7 kg and a diameter of 68.2 cm is attached to a string of length 1.1 m. It moves in a circular path at constant speed, 3.0 m above the ground. The string makes a constant angle of 17 ° with respect to vertical. L m (a) What is the speed of the ball? (b) What is the tension in the string?

A small airplane of mass 1200 kg is doing a horizontal turn. The turn requires the pilot to bank the plane with an angle 0 =24° as shown in the figure. If the radius of the turn is 2400 m, what is the speed of the airplane measured in m/s? L Ө Fg

A centripetal force of 36.1N is exerted in a 2.5kg sphere causing it to rotate uniformly on a horizontal circle with radius of 1.5m. Ignore air resistance and gravity. What is the speed of the sphere in m/s

An airplane is flying north. It makes a gradual 180° turn (at any instant, the turning angle is less than 90°) at constant speed of 415.5 km/h, changing its direction of travel from north through east to south in 36.5 s. The centripetal acceleration of the plane for this turn in m/s2 is: Answer: The force of gravitational attraction hetween tuuo nhinntamith
