###### A 60 kg electrician is shot from large spring cannon. The force constant; k, of the spring is 1100 N/m_ The clown is put inside the cannon compressing the spring with a force of 4400 N: The inside of the cannon generates constant 40 N frictional force during the 4.0 m that he moves in the barrel: The end of the barrel is 2.5 m above the clown's initial rest position:(a) Draw a free body diagram showing all the forces on the clown as he moves inside the barrel. Which forces are doing work, a
