1. Ex. 1: The highest waterfall in the world is Angel Falls in Venezuela, with a total drop of m. Express this drop in feet.

2. Ex. 2: Express the speed limit of 65 miles/hour in terms of meters/second.

3. Ex. 3: A tall building casts a shadow that is 67. 2 m long
Ex. 3: A tall building casts a shadow that is 67.2 m long. The angle between the sun’s rays and the ground is θ = 50.0°. Determine the height of the building.

4. Ex. 4: A lakefront drops off gradually at an angle θ. At 14
Ex. 4: A lakefront drops off gradually at an angle θ. At 14.0 m offshore the depth is 2.25 m. (a) What is the value of θ ? (b) What would be the depth d of the lake at a distance of 22.0 m from the shore?

5. Ex. 7: A displacement vector r has a magnitude of r = 175 m and points at an angle of 50.0° relative to the x axis. Find the x and y components of this vector.

6. Ex. 8: A jogger runs 145 m in a direction 20. 0° east of north (dis
Ex. 8: A jogger runs 145 m in a direction 20.0° east of north (dis. vector A) and then 105 m in a direction 35.0° south of east (dis. vector B). Determine the magnitude and direction of the resultant vector C for these two displacements (using component addition).
