Episode 18 focuses on how to utilize graphs associated with momentum and impulse through three examples. Two railway cars collide in a velocity time graph. A fancy electric car accelerates (3:59) and a mischievous friend fires a slingshot in a force time graph (5:01). Momentum vs time graphs are less commonly used (6:16).The Question of the Day asks: (7:06) A bullet of mass “m” is shot vertically at speed “v” into a wooden block of mass “10m.” After becoming embedded in the block, what height “h” does the bullet-block system reach?Thank you for listening to The APsolute RecAP: Physics 1 Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
