10. Each of the following vectors are given in terms of components. Draw the vector, label an angle that specifies the vector's direction, and then find the vector's magnitude and direction. a. Vx = 20 m/s, Vy = 40 m/s b. ax = 2.0 m/s, a, = 6.0 m/s 11. If you go to a ski area, you'll likely find that the beginner's slope has the smallest angle. Use the concept of acceleration on a ramp to explain why this is so. 12. A projectile is launched from ground level at an angle of 30 degrees above the horizontal. Neglect air resistance and consider the motion from just after the moment it is launched to just before the moment it lands on the ground. Use the following choices (a. thru f.) to answer questions A through D a. Just before landing on the ground. b. The projectile's velocity is never zero. c. Just after launch. d. Halfway to the highest point. e. At the highest point. f. Halfway back down to the ground. g. Never A. When is the projectile's velocity equal to zero? B. When does the projectile have the smallest speed? C. When does the projectile's speed equal its launch speed? D. After launch, when does the projectile's velocity equal its launch velocity? A. B. C. D. 10. Each of the following vectors are given in terms of components. Draw the vector, label an angle that specifies the vector's direction, and then find the vector's magnitude and direction. a.
