Place a ball on a book and walk with the book in uniform motion. Note that you don't really have to do anything to the ball to keep the ball moving with constant velocity (relative to the ground) or to keep the ball at rest (relative to you). Then stop suddenly, or abruptly change your direction or speed. What does Newton's first law of motion predict for the motion of the ball (assuming that the interaction between the ball and the book is small)? Does the ball behave as predicted? It may help to take the point of view of a friend who is standing still, watching you.
A 1500 kg car located at has a momentum of . What is its location 10 s later?
You jog at a steady speed of 2 m/s. You start from the location and for the first 200 s your direction is given by the unit vector . Next you jog for 300 s in the direction given by the unit vector . Finally you jog for 150s in the direction given by the unit vector . (a) Now what is your position? (b) What was your average velocity?
What is the velocity of aobject when its momentum is?
In Figure , the vector points to the location of object 1 and points to the location of object 2 . Both vectors lie in the plane. (a) Calculate the position of object 2 relative to object 1 , as a relative position vector. (b) Calculate the position of object 1 relative to object 2 , as a relative position vector.
