2 @ Add the three vectors, and find the resultant's magnitude B direction . If you report the angle @ in polar coordinates , be sure you are in the correct quadrent - otherwise just draw the triangle and O 4 20 0 + 58 + 7so 2001 seasoning $ 3 e b Add a fourth vector, then recompute the resultant's magnitude $ direction . your vector must be diagonal, and make sure its magnitude $ angle have a decimal places ( 1Vol = 40.62, 8 = 55.55)That 4 A car starts from rest, and speeds up to + 30m/s, in GO seconds. Then, it stays at that velocity for 400 meters. next, it [ you choose]. Finally, make sure the it you choose slopes match ( end of first a Finish designing this problem ( use a decimal points) part of trip and find the total time elapsed & displacement and beginning b of second part ) Draw ( with correct numbers) the position, velocity, and acceleration graphs, for the trip
