PHY 1010U Lecture Notes - Lecture 4: Acceleration, Main Source, Angular Acceleration
Document Summary
Phy1010 tutorial 2 vectors, projectile motion, circular motion. A vector is a quantity described by both a magnitude and a direction. Unit vectors have magnitude 1 and no units. Any vector can be written in the component form: kajaiaa x y z. To find the components of a vector on axes, or its magnitude and angle, use trigonometry. Answer: 23. 2 m, 30. 9 s of e. Problem 2 a field mouse trying to escape a hawk runs east for 5. 0 meters, darts south east for 3. 0 meters, then drops 1. 0 meter straight down into its burrow. Projectile motion v s v ta tv i sa (2. 2 v i a s i f f. Problem 3 a supply plane needs to drop off some supplies to scientists working on a glacier in greenland. The plane flies 100 meters above the glacier at a speed of 150 m/s. Problem 4 - you and your best friend are playing catch.
