During a hammer thrower's practice swings, the 7.1−kg head A of the hammer revolves at a constant speed v in a horizontal circle as shown. If ρ = 0.93 m and θ = 60∘, determine (a) the tension in wire BC, (b) the speed of the hammer's head. TBC = 80.4 N and vA = 2.3 m/s TBC = 40.2 N and vA = 1.15 m/s TBC = 20.4 N and vA = 3.3 m/s TBC = 50.6 N and vA = 4.3 m/s

During a hammer thrower's practice swings, the

7.1 - k g

head

A

of the hammer revolves at a constant speed

v

in a horizontal circle as shown. If

ρ = 0.93 m

and

θ = 60^{\circ}

, determine (a) the tension in wire

B C, (b)

the speed of the hammer's head.

T_{B C} = 80.4 N

and

v_{A} = 2.3 m / s

T_{B C} = 40.2 N

and

v_{A} = 1.15 m / s

T_{B C} = 20.4 N

and

v_{A} = 3.3 m / s

T_{B C} = 50.6 N

and

v_{A} = 4.3 m / s
