A ball is being rotated at the end of a 4-meter long string such that it is describing a circular path. If the angle that the string makes with the vertical is 40°, and the ball has a mass of 10-Kg, determine the speed of the ball and the tension in the string

A person drives a car around a circular cloverleaf with a radius of 64 m at a uniform speed of 10 m/s. (a) What is the acceleration of the car? (b) Compare this answer with the acceleration due to gravity as a percentage.

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 ball of mass m is tied to one end of a string of length L, the other end of which is fixed to the ceiling. The ball is then set in motion at a constant speed in a horizontal circle of radius R less than L around the axis that the string would make if the ball were to hang at rest (the string thus makes a constant angle theta with the vertical direction). Determine how long it takes the ball to go around the circle once in terms of m, vector g, L, and theta (Comment: an object moving as described is called a conical pendulum.)
