of 200 m/s. What impulse could be delivered by this rocket?
A. 0.75 kg•m/s
B. 1.33 kg•m/s
C. 2000 kg•m/s
D. 30,000 kg•m/s

Sure, here is a transcription of the image suitable for an educational website: --- **Question 53:** A 50.0 kg child is riding in a 120.0 kg bumper car at an amusement park. The child drives the bumper car at 4.5 m/s head-on into the wall of the ride and rebounds at \(\frac{1}{3}\) the speed. What is the magnitude of the change in momentum of the child in the bumper car? - **A.** 375 kg·m/s - **B.** 510 kg·m/s - **C.** 720 kg·m/s - **D.** 1020 kg·m/s **Question 54:** In a rocket test facility, aerospace engineers are testing a rocket’s propulsion ability during a short test blast. The engineers measure a 150-kg mass flow of exhaust gas through the engine at an average velocity of 200 m/s. What impulse could be delivered by this rocket? - **A.** 0.75 kg·m/s - **B.** 1.33 kg·m/s - **C.** 2000 kg·m/s - **D.** 30,000 kg·m/s **Question 55:** A steel ball, a rubber ball, a wet ball of clay, and a golf ball of the same mass are dropped from rest 10.0 m above the ground. The steel ball rebounds from the ground at a speed \(\frac{1}{4}\) of its impact speed, the rubber ball rebounds with a speed \(\frac{3}{4}\) of its impact speed, the wet ball of clay sticks to the ground and comes to rest, and... --- These questions explore concepts in physics related to momentum, impulse, and material properties in collisions.
