I posted this in the Intro Physics section, but found now help, so hopefully one of you can help me out. Here are the problems: 1. A football player runs directly down the field for 35 m before turning to the right at an angle of 25degrees from his original direction and running an additional 15 m before getting tackled. What is the magnitude and direction of the runner's total displacement? (answers are 49m, and 7.3degrees, but how do you get them??) 2. A plane travels 2.5 km at an angle of 35degrees to the ground, then changes direction and travels 5.2 km at an angle of 22degrees to the ground. What is the magnitude and direction of the plane's total displacement?? (I dont know the answer to this one) I've tried over and over to figure it out, usually attempting to split the diagram into its X and Y components, but I cant seem to figure them out Any help would be very appreciated.
