1) A car decelerates from a speed of 50 m/s to rest in 107
meters. What is the magnitude of the acceleration? How long did
this event take?
2) How fast is a car traveling that accelerates from rest at 4
m/s2 over a distance of 287 meters?
3) A car traveling at 36 m/s passes a policeman who immediately
accelerates at 3 m/s2 in pursuit. How long does it take the
policeman to catch the speeder?
4) A car traveling at 40 m/s passes a policeman who immediately
accelerates to catch the speeder. If the officer catches the
speeder in 16 seconds, what is the policemans acceleration?
5) A car traveling 20 m/s hits a telephone pole and the front
end compresses 0.5 meters as it comes to a stop. Calculate the
acceleration? How much time elapses during this event?
6) How much time does it take for a plane to change its speed
from 100 m/s to 500 m/s with a uniform acceleration in a distance
of 1200m?
7) The first 10 meters of a 100-meter dash are covered in 2
seconds by a sprinter who starts from rest and accelerates with a
constant acceleration. The remaining 90 meters are run with the
same velocity the sprinter had after 2 seconds. a) Determine the
sprinter's constant acceleration during the first 2 seconds.
b) Determine the sprinters velocity after 2 seconds have
elapsed.
c) Determine the total time needed to run the full 100
meters.
8) A spacecraft traveling at 1200 m/s is uniformly accelerated
at the rate of 150 m/s2 by burning its second stage rocket. If the
rocket burns for 18 s, what is the final velocity of the craft?
9) An airplane requires 20 seconds and 400 meter runway to
become airborne, starting from rest. What is the velocity at which
it leaves the ground?
10) An airplane requires 20 seconds and 400 meter runway to
become airborne, starting from rest. What is the velocity at which
it leaves the ground?
