A car initially traveling northeast (45° N of E) at 28.3 m/s takes 6.0 s to turn to the east. After the turn, the car is traveling due east at 20.0 m/s. What is the value and direction of the change in velocity?

Answer 1

change in velocity= finalvelocity-initialvelocity

breakthe initial velocity into N,E components.

Vi=28.3*.707N+28.3*.707E
Vf=20 E

subtract. change in velocity=Vf-Vi

Answer 2

thank you
