Question

A "swing" ride at a carnival consists of chairs that are swung in a circle by 17.9 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 193 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.

Answer 1

need the drawing for a solution

or, at least, more data

Answer 2

You are a pirate working for Dread Pirate
Roberts. You are in charge of a cannon
that exerts a force 10000 N on a cannon ball
while the ball is in the barrel of the cannon.
The length of the cannon barrel is 1.7 m and the cannon is aimed at a 38◦angle from the ground.The acceleration of gravity is 9.8 m/s^2.
If Dread Pirate Roberts tells you he wants the ball to leave the cannon with speed V-not = 76 m/s, what mass cannon ball must you use?
Answer in units of kg.
