Problem 1- In an inelastic collision, what formula would you use in analyzing the collision? Because you may be asked to solve for any of the variables in a given problem, please give the entire formula. Use m1 and m2 for the masses of the objects, v1 and v2 for the initial speeds, and vf for the speed of the combined mass.

Problem 2- A 2.5-kg cannon is loaded with a 75-gram tennis ball and placed on the floor. A photogate measurement determines that the cannon recoiled backwards with a speed of 6 m/s. Determine the speed of the ball.

A. 180 m/s

B. 150 m/s

C. 250 m/s

D. 200 m/s

Problem 3- A 1000 kg plane travels with constant velocity of 700. kph. What is the momentum of the plane?

A. 1.0 x 105 kg m/s

B. 7.0 x 104 kg m/s

C. 1.94 x 104 kg m/s

D. 1.94 x 105 kg m/s

Problem 4- A 200 Newton net force is applied to a tractor in a field. If the 10,000 kg tractor starts off at rest and ends up travelling with a speed of 2m/s. How long has this force been applied to the tractor?

A. 75 s

B. 50 s

C. 100 s

D. 83 s

Problem 5-Two billiard balls, each of mass 450 g, roll towards each other head on: one with speed of 4.3 m/s and the other with a speed of 6.5 m/s. After the collision, the one that was traveling faster reverses its direction and travels at 3.8 m/s. What is the velocity of the other ball?

A. 6 m/s

B. 2.2 m/s

C. 3.8 m/s

D. 4.3 m/s

In an elastic collision, what formula would you use in analyzing the collision? Because you may be asked to solve for any of the variables in a given problem, please give the entire formula. Use m1 and m2 for the masses of the objects, v1 and v2 for the initial speeds, and v1f and v2f, for the final speeds of the two masses.
