Measured magnitude of cart velocity = ___________ m/s

Table 1: Cart x and y velocities versus angle from the x-axis

Angle (degrees)	vx (m/s)	vy (m/s)	(m/s)
45	0.325	0.326
30	0.329	0.324
15	0.327	0.324
60	0.323	0.323

Questions and Analysis

1. Summarize the four relationships between vx, vy, , and below.

2. If any two values of vx, vy or are known, angle can be calculated using the equations found in this lab. Use the values from Table 1 to calculate the angle for each of the trials. Try to use all three equations. Show all of your work below.

3. A spy is trying to escape an enemy country in a plane that is going its maximum speed of 100 m/s. To avoid radar detection, she must fly at an angle of 25oto the northern border. See Figure 4. How fast is she traveling in the direction toward the northern border (north)? If she is 500 km south of the border, how much time will it take her to reach the border? Show all of your work below.
