A physics instructor whirls a tennis ball of mass m attached to a string in a circular path of radius R in horizontal plane over his head. When the ball has a speed s the tension in the string is 10 N.
A.) If the ball speed is increased by a factor of 2 and the radius of the circle is kept the same, what is the tension in the string? Explain.
a. 10 N
b. 20 N
c. 30 N
d. 40 N
e. There is not enough information to calculate the Tension

A child swings a tennis ball attached to a 0.633-m string in a horizontal circle above his head at a rate of 4.50 rev/s. (a) What is the centripetal acceleration of the tennis ball? (b) The child now increases the length of the string to 1.00 m but has to decrease the rate of rotation to 3.50 rev/s. Is the speed of the ball greater now or when the string was shorter? (c) What is the centripetal acceleration of the...
