1. In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 22.0 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 1.30 m, calculate the angular acceleration.

The hammer throw is a track-and-field event in which a 7.30-kg ball (the hammer) is whirled around in a circle several times and released. It then moves upward on the familiar curved path of projectile motion and eventually returns to the ground some distance away. The world record for the horizontal distance is 86.75 m, achieved in 1986 by Yuriy Sedykh. Ignore air resistance and the fact that the ball was released above the ground rather than at ground level....

The hammer throw is a track-and-field event in which a 7.2-kg ball (the ''hammer''), starting from rest, is whirled around in a circle several times and released. It then moves upward on the familiar curving path of projectile motion. In one throw, the hammer is given a speed of 23.0 m/s. For comparison, a .22 caliber bullet has a mass of 2.6 g and, starting from rest, exits the barrel of a gun with a speed of 400 m/s. Determine...

The hammer throw is an Olympic event where a 7.5 kg metal ball is attached to a 1.2 m long wire, as shown in the diagram. One such competitor was observed to swing the hammer around in a horizontal circle with an average angular acceleration a = 5.6 rad/s?. After 3 seconds the hammer was released. (a) Calculate the angular velocity and tangential speed of the metal ball just before it is released. (b) Calculate the number of revolutions the...

1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...

Please answer ALL parts.
A phonograph turntable driven by an electric motor accelerates at a constant rate (i.e., constant angular acceleration) from 0 to 33.33 revolutions per minute in 2 minutes. The turntable is a uniform disc of mass 1.5 kg and radius R = 13 cm, as indicated in the figure. The radius of the driving wheel is r = 2.0 cm. What is the torque required to drive the turntable at this angular acceleration? If the driving wheel...
