Mrs. P-D’s Class: 10/20

• If you walk 6 m east, 14 m north, and 2 m west, what is your displacement? What is your distance?

​

​

​

To Do:

• Group/Individual Vectors, Relative Velocity, and Projectile Motion Review Sheet due by the end of class Monday (10/23)
• The Physics Classroom Virtual Projectile Motion Lab (Horizontal Projectiles and Projectiles Launched at an Angle) due by 10/23 (Monday)
• Projectile Motion CB due 10/23 by 11:59 pm
• Vector, Relative Velocity, and Projectile Motion Test (10/25 for 5th and 7th and 10/26 for 4th)

Displacement

x₁ = +6 m y₁ = 0 m

x2 = 0 m y2 = +14 m

x3 = -2 m y3 = 0

xT = +4 m yT=+14 m

​

R = √14² + 4² = 14.6 m

Θ = tan⁻¹(4/14) = 15.9° E of N

OR 74.1 N of E
