1. State:

a. Newton's First Law

b. Newton's Second Law

c. Newton's Third Law

d. The Law of conservation of energy.

e. The Physics Definition of Work.

f. The Work-Energy Thereom.



2.The Professor is taking a joy ride on his new invention. The rope is tied securely to his waist.

a. Name each force acting on the professor. You must include the name of the object applying the force.

b. Name the reaction force to each force applied to the professor. You must include the name of the object applying the force.




3.The figures below depict eight cannons shooting shells into the air. All of the cannons are aimed at the same angle of 35 degrees. All of the cannons are identical. The shells are all the same size and shape, but the masses of the shells, as well as their speeds as they leave the cannons, are different. The values of these variables are specified in the figures.

Rank these situations from highest to lowest on the basis of the acceleration at the highest point reached by the shells. (We assume for this situation that the effect of air resistance can be ignored.)



4. If a force F = (3i - 2J) N is applied to an 8 kg object over the displacement r = (2i + 5j) m ;

a. Find the net work done on the object.

b. Find it's total change in kinetic energy.
