5) During the last rotation, a hammer thrower maintains a constant acceleration of his hammer. From 28 m/s, the hammer attains a velocity of 30 m/s.a) If the radius of the hammer trajectory is 1.2 m, determine the total linear acceleration when the hammer has covered 3/4 of the last rotation.b) How far will the throw be if the initial angle is 43°, 1.9 m above the ground?

We know that the third equation of the angular motion is given as ω2=ω02+2αθ where ω is the…

5) During the last rotation, a hammer thrower maintains a constant acceleration of his hammer. From 28 m/s, the hammer attains a velocity of 30 m/s.

a) If the radius of the hammer trajectory is 1.2 m, determine the total linear acceleration when the hammer has covered 3/4 of the last rotation.
b) How far will the throw be if the initial angle is 43°, 1.9 m above the ground?
