Please help me answer number 3 with complete solution

#1. Given the vectors A, B, and C: Å- 110 m, 60 South of West B = 220 m, 30° East of South C = 170 m, 20" North of East a) Find the resultant vector using the graphical method. Indicate the scale that you use. b) Find the x and y components of each vector. Tabulate your results. Do not forget to include the algebraic sign. Vector X - component y - component e) Find the vector sum or the resultant vector R. #2. Draw each of the following vectors, then express these vectors in terms of unit vectors. a) d = (100 m, 45" below + x axis) b) = (300 m/s, 20 above + x axis) e) d = (5.-y axis) #3. A car slows down uniformly from a speed of 18.0 m/s to rest in 5.00 s. How far did it travel in that time? Make an x vs t, v vs t, and a vs t graphs of the motion of the car. #4, An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 135 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.00 mis", how much time passes before the police car overtakes the speeder (assumed moving at constant speed)? #5, A baseball is hit almost straight up into the air with a speed of about 20 m/s. (a) How high does it go? (b) How long is it in the air?
