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...

Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...

Suppose a 0.390 kg ball is thrown at 17.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure below. (a) Calculate the final linear velocity (in m/s) of the person, given his mass is 90.0 kg x m/s 07 (b) What is his angular velocity (in rad/s) if each arm is 3.00 kg? You may treat the ball as a point mass and treat the person's arms as uniform...
