4. Acceleration 2. An object is launched with an initial velocity of 3 m/s [right] and 4 m/s [up]. At the highest point in its trajectory, the acceleration of the object is: A. 3 m/s 2 [right] B. 4 m/s 2 [up] C. 9.8 m/s 2 [down] D. zero

5. Acceleration 2. An object is launched with an initial velocity of 3 m/s [right] and 4 m/s [up]. At the highest point in its trajectory, the acceleration of the object is: A. 3 m/s 2 [right] B. 4 m/s 2 [up] *C. 9.8 m/s 2 [down] D. zero

6. Horizontal Speed 3. At the highest point in its trajectory, the speed of the object from Question 2 is: A. 3 m/s B. 4 m/s C. 5 m/s D. zero

10. Final Speed Again 5. Three objects are launched from a height of 5 m, each with an initial speed of 5 m/s. Object A is launched straight up, Object B is launched horizontally, and Object C is launched straight down. Which object is travelling the fastest when it hits the ground? A. Object A B. Object B C. Object C D. The speeds are the same.

11. Final Speed Again 5. Three objects are launched from a height of 5 m, each with an initial speed of 5 m/s. Object A is launched straight up, Object B is launched horizontally, and Object C is launched straight down. Which object is travelling the fastest when it hits the ground? A. Object A B. Object B C. Object C *D. The speeds are the same.

12. Horizontal Speed A rescue airplane drops a relief package while it is moving with a constant horizontal speed. Assuming that air resistance is negligible, where will the package land relative to the plane? Explain. Beneath the plane (position B) because the horizontal component of the velocity will not change.

13. Problem Solving A projectile is launched from ground level with an initial velocity of 12 m/s [45 o above the horizontal]. (a) How long is the object in the air and (b) how far horizontally does the projectile travel before it lands?
