Question
NAME: Pre-discussion 2-Vectors & Projectile Motion is 400 m and is directed 60.00 1.-( has a length of 25.0 m and is directed at 45.0° below horizontal. above horizontal. Find the magnitude and direction of A + 2. A ball is launched with an initial velocity Do-25.0 m/s and a 50° angle from the top of the cliff at point It takes 3.91 seconds for the ball to reach point 3. The coordinate system is given in this problem. peak Vo-25.0 m/s 50° cliff h- 50 m ground What is the numerical values of a, and ay for the ball in motion? State your answers without using any calculation in this part (a) (b) Find the horizontal traveling distance from point 1 to point 3. (c) Find the maximum height (at point 2) of the ball with respect to the origin shown in the graph.Explanation / Answer
1. A = 25 (cos45i - sin45 j)
A = 17.7 i - 17.7 j
B = 40 (cos60i + sin60j)
B = 20i + 34.6j
A + B = 37.7i + 16.9 j
magnitude = sqrt(37.7^2 + 16.9^2) = 41.3 m
