physics

A driver of a car traveling at 15.9 m/s applies
the brakes, causing a uniform deceleration of
1.7 m/s2.
How long does it take the car to accelerate
to a final speed of 13.0 m/s?
Answer in units of s.
b) How far has the car moved during the
braking period?
Answer in units of m.

  1. a) Review and apply the definition of acceleration.
    a = (Change in velocity)/(time interval)

    b) distance = (average velocity)*time
