CHAPTER 2: MOTION IN ONE-DIMENSION
ONE DIMENSIONAL MOTION
A car starts from a state of rest and drives along a level, straight road. For the first
30 s, the car speeds up with a constant acceleration of 2.50 m/s
, after which it
continues at the constant velocity that it has acquired for the next 5.00 minutes, at
which time the brakes are applied, and there is an acceleration of -2.2 m/s
the car stops. What is the total displacement of the car from its starting point, and
the total time of travel?
The velocity of an object as a function of time is given by
is in seconds. If the object has a position
= 8.00 m at
= 2.00 s, what is
the position of the object at time
= 5.00 s?
EQUATIONS OF MOTION
A plane has a mass of 360,000 kg takes-off at a speed of 300 km/hr.
What should be the minimum acceleration to take off if the length of the runway is 2.00
