**Answers to any or all these questions would be very helpful!!!!!**


There are two different moving objects: a toy car that is run by a small motor and an unpowered car that rolls down an incline.

a) Do you expect either of these objects to exhibit constant-velocity motion? If so, why?



b) What will the position vs time graph look like for such an object in constant-velocity motion?


c) Do you expect either of these objects to exhibit constant-acceleration motion? If so, why?


d) What will the position vs time graph look like for such an object in constant-acceleration motion?

Explanation / Answer

please rate only the best answer as lifesaver please rate all answers as even if one answer is left unrated no one would get any points a)the car with constant power can be moving with constant velocity because in steady state the power given by motor would become equal to power dissipated due to friction. the other car would be constantly under force of gravity and its speed will keep on increasing b)in constant velocity motion, the position vs. time graph would be a straight line with slope equal to speed. c)the unpowered car would exhibit constant acceleration motion since total force on car = gravity force - friction force, would be a constant and force = mass*acceleration d)the position vs. time graph of a constant acceleration motion would be a increasing curve with increasing slope
