The men's hammer throw is a track-and-field event in which a 7.69-kg metal ball attached to a wire and handle is thrown as far as possible. Suppose that for the purpose of warming up before a meet, an athlete swings a "hammer" around in a horizontal circle of radius r = 99.2 cm such that the wire makes an angle of θ = 57.8° with the vertical direction.Â
y+ is up, x+ is to the left.
a) what is the tension on the cable? (answer in N)
b) what is the speed of the metal ball? (in m/s)
