  1. Honors physics Getting ready

  2. Throwing a spear If I throw a spear at 25 m/s at an angle of 20 degrees…. What other angle could I throw it, with the same speed, and achieve the same distance?

  3. Throwing a spear If I throw a spear at 25 m/s at an angle of 20 degrees…. What other angle could I throw it, with the same speed, and achieve the same distance? 70o (distance would be 40.9m)

  4. Kick a ball into the air at an angle Which is greater Horizontal velocity? or Vertical velocity? or Resultant velocity?

  5. Kick a ball into the air at an angle Which is greater Horizontal velocity? or Vertical velocity? or Resultant velocity? Because the resultant is the result of the addition of the other two vectors.

  6. Ball rolls off and a ball drops from a table … Which hits the ground first? Which has the greater horiz. Velocity? Which has the greater vert. velocity? Which has the greatest overall velocity?

  7. Ball rolls off and a ball drops from a table … Which hits the ground first? Both hit same time Which has the greater horiz. Velocity? Rolling Which has the greater vert. velocity? Both same Which has the greatest overall velocity? rolling

  8. James Bond jumps steps out of a plane… The plane is flying horizontally at 75 m/s at an elevation of 1300 m. How far horizontally from his starting point will Bond….. James Bond land, I he doesn’t get a parachute on the way down.

  9. James Bond jumps steps out of a plane… The plane is flying horizontally at 75 m/s at an elevation of 1300 m. How far horizontally from his starting point will Bond….. James Bond land, I he doesn’t get a parachute on the way down. 1221 m

  10. Super FrogMan can jump With a speed of 30 m/s at an angle of 30o. How far can he jump in a single bound?

  11. Super FrogMan can jump With a speed of 30 m/s at an angle of 30o. How far can he jump in a single bound?

  12. Super FrogMan can jump With a speed of 30 m/s at an angle of 30o. How far can he jump in a single bound? 79.56 m

  13. A ball rolls rapidly off a roof…… • (which is at an angle of 40o below the horizontal) at a speed of 15 m/s. How far from the house will the ball land if the roof is 15 m above the ground?

  14. A ball rolls rapidly off a roof…… • (which is at an angle of 40o below the horizontal) at a speed of 15 m/s. How far from the house will the ball land if the roof is 15 m above the ground? 5.33 m

  15. Dazed and confused…. You walk 40 m in the positive x direction, 30 m at a 20o above the positive x axis and 15 m at 10o below the negative x axis. What is your displacement? 53.95 m 8.2o N of E

  16. Aquaman swims across a 100m river… At 5m/s in a current that is directed 3 m/s downstream. How far downstream will he be when he beaches himself?

  17. Aquaman swims across a 100m river… At 5m/s in a current that is directed 3 m/s downstream. How far downstream will he be when he beaches himself?

  18. Aquaman swims across a 100m river… At 5m/s in a current that is directed 3 m/s downstream. How far downstream will he be when he beaches himself? 60 m

  19. Goooooooooooooaaaaaaaaalllll???? 50 meters from a 5 m goal post, PVHS kicker kicks the ball at 15 m/s at an angle of 25o. Does he score a goal?

  20. Goooooooooooooaaaaaaaaalllll???? 50 meters from a 5 m goal post, PVHS kicker kicks the ball at 15 m/s at an angle of 25o. Does he score a goal? -43.2 m below horizontal. Doesn’t make the goal.
