3) The previous Dynamics TAs had so much fun at the bumper cars that decided to go again for round 2. This time, they thought it'd be a great idea if David hit Will first, and then Caryn would hit Will after. David is traveling at 15 ft/s to the right, meanwhile Caryn is traveling at 20 ft/s to the left. Will chose the broken car once again, so he is not moving. Assume Will weighs 160 lbs., Caryn weighs 120 lbs., David weighs 175 lbs. and each car weighs 300 lbs. If the coefficient of restitution between the bumper cars is 0.75, determine Will's velocity after each impact.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Problem 2: A rocket is launched from the ground, straight up, from rest. The expelling gases from the bottom of the rocket provide it with a constant upward acceleration a. After 20 sec, the rocket reaches a height of 6500 m. At this point, the rocket depletes its fuel supply and the engines of the rocket are no longer working. At this point, the rocket goes into free fall, with an acceleration of –9.8 m/sec2. The left part of the figure below applies to parts (a)-(b). (a) What is the rocket's initial upward acceleration a? (b) What is the rocket's speed v, 20 sec after take-off? Hint: The answer is v = 650 m/sec. For parts (c)-(d), the rocket engines are now off. We will redefine the time to t = 0. The final properties for when the engines were on make the initial properties for when the engines are off: y0 = 6500 m, vo = 650 m/sec, and the acceleration is now a = -g, with g = 9.8 m/sec?. The right part of the figure below applies to parts (c)-(d). (c) What is ymaz, the largest height…
