At the beginning of a 3.0-h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 239 km/h in the northwest direction (45° west of north). a. Which of the following are the initial and final velocity vectors? SEE ATTACHMENTS b. Find the magnitude of the change in velocity. anser in km/h c. Find the change in direction of your velocity. Enter the angle in degrees where negative indicates north of west and positive indicates south of west. answer in degrees d. What is the magnitude of your average acceleration during the trip? answer in km/h^2

During a football game Aiden kicks a ball from the ground at the 30-yard line. He gives the ball an initial speed of 20 meters per second, at an initial angle of 36.9 degrees. a. One second after the kick how high is the ball above the ground measured in feet? b. How far away will the ball land on the ground measured in yards?
