  1. Physics Review Game:Midterm Ediçion Senor Vannucci

  2. 9) A person on a unicycle accelerates from rest to 10 m/s in 2 seconds.  What is their acceleration?

  3. (continuing from previous) In how much distance did they complete this acceleration?

  4. Describe a car’s change in motion when the velocity and acceleration are in opposite directions.

  5. Draw a position vs. time graph for the following scenario: A car starts at 0 m and 0 m/s and is speeding up in a positive direction

  6. (continuing from previous problem) Now, draw a velocity versus time graph for the same situation: a car starting at rest that is accelerating in a positive direction

  7. A girl jumps into the air with initial velocity of 3 m/s. a.  What is the girl’s hangtime? b.  How high did her feet get off the ground?

  8. A book is tossed in the air reaching a max height of 5m above the person’s hands who tossed it. a. How long will it take the book to get to its max height? b. How long will the total time of flight be for the book? c.  With what initial speed does the book leave the person’s hands?

  9. Using the ticker tape picture in your review packet, find the velocity of the top tape. You will need a ruler

  10. A Lasso is twirled in a circle.  Making one revolution every .7 seconds.  The length of the lasso from the cowboys hand to the edge is 1.2 m.  What is the speed of the loop at the end of the lasso?

  11. A ski lift takes a skier 1.2 km vertically up to the top of a mountain. The skier then skis down the slope for 4.8 km. What is the angle of the slope? (Hint: draw a sketch – it’s a triangle)

  12. A bullet is fired and a bullet is dropped simultaneously from the same height.  Which bullet hits the ground first?  or do they hit at the same time?  Explain your reasoning.

  13. Draw a strobe photo of a dropped object and a horizontally fired projectile.  Label Velocity vectors Vx, and Vy on each picture.  Draw the position of each projectile at 0,1,2, and 3 seconds into its flight.  Use the strobe photo to explain how it moves in the x direction (constant velocity or accelerated) and how it moves in the y direction (constant velocity or accelerated).  Explain using the strobe photo why both objects fall at the same rate

  14. Final Question:A rocket is fired from ground level with an initial velocity of 27.0 m/s, 30.0 above the horizontal. Find the:Time of flight before hitting the ground Maximum heightHorizontal distance traveled before hitting the ground
