A hammer thrower accelerates the hammer (mass = 7.90 kg ) from restwithin four full turns (revolutions) and releases it at a speed of26.0 m/s .
1. Assuming a uniform rate of increase in angular velocity and ahorizontal circular path of radius 1.50 m/s , calculate the angularacceleration. Ignore gravity.
a=_________________ rad/s^2
2. Assuming a uniform rate of increase in angular velocity and ahorizontal circular path of radius 1.50 m , calculate the (linear)tangential acceleration. Ignore gravity
a tan=______________ m/s^2
3. Assuming a uniform rate of increase in angular velocity and ahorizontal circular path of radius 1.50 m, calculate thecentripetal acceleration just before release. Ignore gravity.
a rad=__________________m/s^2
4. Assuming a uniform rate of increase in angular velocity and ahorizontal circular path of radius 1.50m , calculate the net forcebeing exerted on the hammer by the athlete just before release.Ignore gravity.
F=______________N
5. Assuming a uniform rate of increase in angular velocity and ahorizontal circular path of radius 1.50m , calculate the angle ofthis force with respect to the radius of the circular motion.Ignore gravity.
theta=______________ degrees
