Problem/Task 1 (10 points). A vector A has following components: Ax = -4, Ay = 5. A vector B has following components: Bx = 7, By = -1. (a) Draw a reference frame and draw each vector. (b) Use a tail-to-head method and draw the resultant for the sum of the two vectors. (c) Calculate the magnitude of the resultant (you can use the strategy from Lab 2) Problem/Task 2 (10 points). A truck travels from one city to another. At first for 2 hours and 5 minutes it travels 80 km due North, then makes a U-turn and for 45 minutes travels 50 km due South, then it stops for a half an hour, then it finally turns East and travels due East for 40 minutes at 60 km/h. (a) What is the total distance that the truck travels? (b) Find the average speed of the track. Problem/Task 3 (10 points). You are on the ground. You shoot a ball up with the initial speed of 20 m/s. Find the maximum height the ball reaches. You can use the exact or the approximate value for the gravitational acceleration (that is up to you)
