A car in stop-and-go traffic starts at rest, moves forward 22m in 8.0s,then comes to rest again. The velocity-versus-time plot for this car is given in the figure. What distance does the car cover in

(a) the first 4.0 seconds of this motion and

(b) the last 2.0 seconds of its motion?

(c) What is the constant speed v that characterizes the middle portion of its motion?

Question: A car in stop-and-go traffic starts at rest, movesforward 17 in 8.0 , then comes to rest again.


A) What distance does the car cover in the last 2.0 seconds of itsmotion?



B)What is the constant speed that characterizes the middle portionof its motion?


Please show each step and explain

A Ford Focus travels 0.250 mi in 19.9 s, starting from rest. Thesame car, when braking from 60 mph on dry pavement, stops in 146ft. Acceleration is constant in each part of motion, but notnecessarily the same acceleration when slowing down as whenspeeding up.

What is the magnitude of the car's acceleration while braking andwhile speeding up?

How long does it take the car to stop while braking from 60mph?

If its acceleration is constant while speeding up, how fast willthe car be traveling after 0.250 mi of acceleration?
