A hammer thrower accelerates the hammer mass 730 kg from, Ask an Expert

Academics

A hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 25.0 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 0.90 m, calculate the following answers.

(a) the angular acceleration

(b) the (linear) tangential acceleration

(d) the net force being exerted on the hammer by the athlete just before release

(e) the angle of this force with respect to the radius of the circular motion
