  1. Final Constant acceleration questions

  2. Q1 • What are the 4 equations connected to constant acceleration? • Why are there so many equations?

  3. Q2 • A construction worker drops a brick from a high scaffold • What is the velocity of the brick after 4.0 s? • How far does the brick fall in this time?

  4. Q3 • Why does a hammer and feather fall with the same rate of acceleration on the moon, but not on Earth?

  5. Q4 • What is the acceleration of a graduation hat at the apex of its flight after it has been tossed into the air vertically?

  6. Q5 • You decide to flip a coin to determine whether to do your physics homework. The coin is flipped straight up. • If the coin reaches a high point of 0.25 m above where you released it, what is its initial speed? • If you catch it at the same height as you released I, how much time did it spend in the air?

  7. Q6 • A baseball pitcher throws a fastball at a speed of 44 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it through a distance of 3.5 m. • Calculate the acceleration of the ball, assuming it is constant.

  8. Q7 • Engineers are developing new types of guns that might someday be used to launch satellites as if they were bullets. One such gun give a small object a velocity of 3.5 km/s while accelerating it through a distance of just 2.0 m. • Over what time interval does the acceleration take place?

  9. Review for quiz Tuesday or Wednesday • Definition of constant acceleration • Comparison of constant velocity and constant acceleration • Use of constant acceleration equations to solve for velocity, acceleration, displacement, time • Free-fall and acceleration due to gravity • Use and limitations of -9.8 m/s2`
