Question 14 (2 points) Why is it important to follow through on a tennis serve, or a golf swing? (Make reference to Newton's Laws and /or Impulse) Paragraph BIU A EVEY + w Question 15 (4 points) Two identical toy cars collide and stick together. One car was moving at 4 m/s to the right, and the other at 2m/s to the left. Afterwards, the coupled cars move at 1m/s to the right. Ek,initial a) Calculate the ratio of total kinetic energy of the cars before and after the collision, Ek finer You may find it helpful to do a sample calculation where you make up the masses of the cars. 6) Give two possible explanations for where the missing kinetic energy went.Question 16 (3 points) A small truck and a large truck have the same kinetic energies. Which truck has the greater momentum? Justify your answer using numerical calculations and or/using formulas. Like the previous question, you may find it helpful to make up specific values. Paragraph BIUVA Ev Ev . . . Application Question 17 (3 points) Elmer Fudd finally gets his chance to shoot Bugs Bunny (it's just a cartoon!). His 115 g bullet travels towards Bugs at a speed of 230 m/s. Bugs, m = 55 kg stops in his tracks and expertly catches the bullet in his teeth. Determine the speed (in m/s, to two decimal places) of Bugs and the bullet after he catches it.Question 18 (3 points) A 0.50 kg mass on a spring has a period of 1.9 seconds. Determine the spring constant of the spring (in N/m, to 2 decimal places). Your Answer: Answer Question 19 (4 points) The force profile for crazy rocket man is given below (note the scale). His 250 kg rocket ship (including his mass) was initially at rest. Calculate the final speed (in m/s, to 2 decimal places) of the rocket ship after 10 seconds of impulse. F 10N t (s)Question 20 (5 points) Two carts undergo a completely elastic collision. Cart 1 is 1kg and is moving at 5m/s to the right. Cart 2 is 2kg and is initially at rest. Determine the speed and direction of each cart after the collision. Initial Velocity Initial Velocity 4 m/s 0 m/'s Mass: 1 kg Mass: 3 kg Paragraph BIUAEEv + v .. . Question 21 (5 points) A 3.0 kg mass is attached to a horizontal spring, with a spring constant of 5.2 N/m. The spring is then compressed 10 cm. Determine the speed of the mass (in m/s, to 2 decimal places) when it is 3 cm from equilibrium. Your Answer:Question 22 (5 points) A 2.00 kg ball (A) is moving at a velocity of 1.00 m/s. It collides with a stationary ball (B) also with a mass of 2.00 kg. After the collision, Ball A moves off in a direction 40.0" to the left of its original direction of motion (up in the diagram). Ball B moves off in a direction 53.0" to the right of the original direction of motion (down in the diagram). Find the speeds of Ball A and Ball B after the collision. You may use any method you like. Hint: The easiest method may be with trigonometry. Try to draw a vector diagram of the momentums: P total = P A, final + P B, final- O Paragraph BIUAEEV +
