Elastic and Plastic Behaviour

Elastic and Plastic Behaviour problem 16

In a catapult shooting competition, an elastic band of length is stretched with an average force of .

  • By how many joules does the elastic energy increase when the rubber is stretched?

  • How much energy does the elastic band give to the pebble that is shot with the catapult when we pull it?

  • Which energy does the pebble have due to the energy received from the elastic band after launch and what is its value?

  • How much work can the pebble do when it hits an obstacle?
