A driver in a car, originally moving at 12.8 m/s, applies the brakes until the car comes to a stop. The car moves a distance of 36.3 m while braking. How much time (in s) did it take for the car to stop? Assume constant acceleration during braking. 5. [-/1 Points] DETAILS WACOLPHYSAV1 2.P.024. MY NOTES ASK YOUR TEACHER An aircraft, traveling northward, lands on a runway with a speed of 60 m/s. Once it touches down, it slows to 6.6 m/s over 770 of runway. What is the average acceleration (magnitude and direction) of the plane during landing (in m/s )? Take the positive direction to be northward. (Indicate the direction with the sign of your answer.) m/ s 2 6. [-/2 Points] DETAILS WACOLPHYSAV1 2.P.025. MY NOTES ASK YOUR TEACHER A driver in a moving car applies the brakes. The car slows to a final speed of 2.70 m/s over a distance of 40.0 m and a time interval of 7.35 s. The acceleration while braking is approximately constant. (a) What is the car's original speed (in m/s) before braking? m/s (b) What is its acceleration (in m/s ) during this time? (The car's initial velocity is in the positive direction. Indicate the directi with the sign of your answer.) m/s2 7. [-/2 Points] DETAILS WACOLPHYSAV1 2.P.028. MY NOTES ASK YOUR TEACHE
