CHAPTER 2: MOTION IN ONE-DIMENSION ONE DIMENSIONAL MOTION Q1) 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 2 , 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 2 until the car stops. What is the total displacement of the car from its starting point, and the total time of travel?
CALCULUS Q2) The velocity of an object as a function of time is given by v = 3 t 2 + 5 t 12 m/s, where t is in seconds. If the object has a position x = 8.00 m at t = 2.00 s, what is the position of the object at time t = 5.00 s?
EQUATIONS OF MOTION Q3) A plane has a mass of 360,000 kg takes-off at a speed of 300 km/hr. i) What should be the minimum acceleration to take off if the length of the runway is 2.00
