Question: A car initially traveling to the right at a steady speed of 25 m/s for 5.0 s applies its brakes and slows at a constant

A car initially traveling to the right at a steady speed of 25 m/s for 5.0 s applies its brakes and slows at a constant rate of 5.0 m/s2 for 3.0 s. It then continues traveling to the right at a steady but slower speed with no additional braking for another 6.0 s.
(a) To help with the calculations, make a sketch of the car’s velocity versus time, being sure to show all three time intervals.
(b) What is its velocity after the 3.0 s of braking?
(c) What was its displacement during the total 14.0 s of its motion?
(d) What was its average speed for the 14.0 s?
