A 55.2 kg ice skater is moving at 4.07 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.805 m around th
pole.
(a) Determine the force exerted by the horizontal rope on her arms.
(b) Compare this force with her weight by finding the ratio of the force to her weight.
A 0.20 kg yo-yo attached to a 0.60 m string is swung in a circle in the horizontal plane. Find the tension in the string if the yo-yo has an angular velocity of 150 revolutions per minute.
A 3-kg block is at rest relative to a parabolic dish which rotates at a constant rate about a vertical axis. Knowing that the coefficient of static friction is 0.5 and that r= 2 m, determine the maximum allowable velocity v of the block.
