A driver is traveling east on a dirt road when she spots a pothole ahead . she slows her car from 14.0 m/s to 5.5 m/s in 6.0 s. What is the cars acceleration? Please show the formula and how to work it out. Thank you!
The kinematic formula I would use is v(f)=v(i)+at so plugging in the values you'd get 5.5=14+a*6 So a= -1.42, the answer is negative because the car is slowing down.
