Homework Answers 1. t = 1.10 s, vf = 10.8 m/s 2. t = 5.10 s, d = m 3. vf = 5,772 m/s 4. d = 19.6 m, vf = 19.6 m/s 5. vf = 13.6 m/s down, d = 7.6 m below

3
Objective Combine vectors to find the resultant.

4
Vector A quantity that shows magnitude and direction Best represented with arrows Same direction, half the magnitude Same magnitude, different direction 6

5
Adding Vectors Tip to Tail Method Tip Tail 213 Resultant Vector

6
Adding Vectors Tip to Tail Method Tip Tail 213 Resultant Vector

7
Adding Vectors Mathematically = R 2 a 2 + b 2 = c 2

8
Adding Vectors A plane can travel 200 km/h. If it is heading south and has a 25 km/h tailwind also heading south, how fast and in what direction is it traveling?

9
Adding Vectors The same plane can travel 200 km/h. If it is heading south and has a 50 km/h headwind blowing north, how fast is it traveling?

10
Adding Vectors The same plane can travel 200 km/h. If it is heading south and has a 50 km/h crosswind blowing west, what is its velocity?

11
Adding Vectors A river boat has a top speed of 12 m/s. If it attempts to cross a river with a current speed of 5 m/s, what will be its velocity?

12
Resolving into Components Right triangle identities Sine, Cosine, Tangent a o h Θ

13
Practice A bullet is shot into the air with a velocity of 100 m/s at an angle of 45° above the horizontal. Find the horizontal and vertical velocities.
