1. Perform calculations using the correct number of significant figures: a. 2.06 x 0.02584 b. 15.3 / 1.1 c. 0.03012 x 0.0030 2. An aircraft starts from rest and reaches a liftoff speed of 33 m/s. What minimum constant acceleration does it require if the aircraft is to be in the air after a take off run of 240 m? 3. A falcon dives at a pigeon. The falcon starts downward from rest with free-fall acceleration. If the pigeon is 76.0 m below the initial position of the falcon, how long does it take the falcon to reach the pigeon? Assume that the pigeon remains at rest.

4. A tennis ball is thrown vertically upward with an initial velocity of 8.0 . What will its speed be when it returns to its starting point (Must show mathematically)? How long will it take for it to reach its starting point?

5. Add the following vectors algebraically and find the magnitude and direction of the resultant displacement. A. 45 m due East B. 25 m due south C. 10 m due West

6. A hiker walks 30.0 km in a direction of 25 South of West and then 45.5 km in a direction of 72 North of West. Find the magnitude and direction of the resultant displacement.

7. A person standing at the edge of a seaside cliff kicks a rock horizontally of the cliff from a height of 52 m and it lands a distance of 35 m from the base of the cliff. What is the speed at which the rock was initially kicked?
