Timmy the angry teen twirls a dead rat (mass = 2 kg) attached to a rusty chain (length = 1m) in a vertical circle. With what velocity should Timmy rotate the rodent so that the chain just goes slack (no force in the chain) at the top?

Answer #1

We got v = 3.13 m/s.

Here we have used g = 9.8 m/s2 but if we use g = 10 m/s2 then we will get v = 3.16 m/s.

If you have any doubt in any part of the solution feel free to ask.

The figure shows a ball with mass m = 0.450 kg attached to the end of a thin rod with length L = 0.415 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically upward position, with zero speed...

A bungee jumper (mass 80 kg) is attached to a 10 m bungee cord attached to the top of a crane. For the first 5 meters of extension, the force exerted by the bungee cord increases by 2 N for every 1 cm. For any further extension, the force increases by only 1.2 N for every 1 cm.. a) Sketch the elastic force vs the length of the bungee cord. b) What is the maximum extension of the bungee cord...
