Can someone do d and e

answer for D and E

11 Given the vectors A, B and C. Find the following: A = 3i + 5j - 2k; B = −4i + 2j + 3k; C = 5i - 8j – 9k 2. (AB) x C L

Same object is first released from h and strikes the ground at the distance d, if it is released now form 2h it will strike the ground at: A. d B. √2 d C. 2d D. 4d

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

Solution for part D and E only

In the example please help with c) and d)
