Homework Statement


If a car has an initial velocity of 8.0m/s, 25degrees and turns in 4.0 s so it ends up traveling at 11.0m/s, 140degrees find:
a)the acceleration
b)the displacement for the 4.0 s

Have a go at it and then come back.
 
ok I will try but I hardly know where to start
 
a)

V1-8.0m/s, -25degrees
V2-11.0m/s,-140degrees
acceleration-
displacement-
time-4.0s

eq.V2=V1+a*t
11.0m/s,-140degrees=8.0m/s, -25degrees+a*4.0s

now I am not sure if this is how you would start this can someone steer me in the right direction?
