Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this video: PROBLEM 1 A girl is riding her bike with a constant velocity of 10 m/s. How far has she gone after 7 seconds? Graph her motion both in x vs t, and v vs. t. Show her displacement on both graphs. PROBLEM 2 A driver is driving at a constant velocity of 20 m/s. She steps on the gas at t=0 and accelerates to 30 m/s with constant acceleration. It took her 4 seconds to accelerate. How far did she go in those 4 seconds? Graph her motion on a v vs t graph and show the displacement on that graph. PROBLEM 3 A biker, biking at 10 m/s hits a tree and comes to a complete stop. Assuming a helmet “crumple zone” of 10 cm, what is the minimum acceleration her head could undergo? How many “g”s is that?
