In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m?

But what affects these kinematic quantities? Below is a figure of the height and range covered by a projectile launched bat the same initial velocity but at different angles. Questions: 1. How do you describe the range covered by the projectile at different projection angles? 2. At what angle/s does it reach the farthest? the nearest? 3. Whatr angles cover the same range? what do you call these angles?Can you have a positive or negative velocity but a position with the opposite value (negative or positive)? Explain why or why not. (Easy to understand) Can you have zero velocity but a positive or negative position? Give an easy example. As you look at the graph for position, what does the slope of the line for distance vs. time tell us? (hint: Δd/Δt) As you look at the graph for velocity, what does the slope of the line for velocity vs. time tell us? (hint: Δv/Δt)
- Solve the given problem by a graphical method. On the same graph, plot position versus time for the car and the trooper. From the intersection of the two curves, read the time at which the trooper overtakes the car. You are driving at a constant speed of 45.0 m/s when you pass a trooper on a motorcycle hidden behind a billboard. One second after your car passes the billboard, the trooper sets out from the billboard to catch you, accelerating at a constant rate of 3.00 m/s2. How long does it take the trooper to overtake your car?The motion of a projectile may be described in terms of range and the maximum height it reaches. But what affects these kinematic quantities? Below is a figure of the height and range covered by a projectile launched bat the same initial velocity but at different angles. Questions: 1.
