The toy car shown will move under its own power at a constant speed. Let’s define the x direction to be along the lab bench to the right as seen from your seat. The y coordinate will be toward the blackboard. Now we’ll place the car on a sheet which we can move to the right relative to the lab bench. We’ll start the car moving toward the blackboard and then drag the sheet to the right along the lab bench at a second speed. Your job is to describe the car’s velocity vector , ( speed and direction) relative to the lab bench .
Assuming that the car moves toward the blackboard (the direction) with a speed of 2 [m/s] relative to the sheetand that the sheet moves to the right on the bench (the xdirection) at a speed of 1 [m/s], the vector velocityof the car relative to the bench is:Question #3 y
Assuming that the car moves toward the blackboard (the direction) with a speed of 2 [m/s] relative to the sheetand that the sheet moves to the right relative to the bench(the direction) at a speed of 1 [m/s], the speedof the car relative to the bench is:Question #4 y x
The angle the car’s velocity vector relative to the benchmakes with the x direction is:Question #5
Summary The velocity of a moving object relative to a fixed set of coordinates can be written as the vector sum of the object’s velocity relative to moving coordinates plus the velocity of the moving coordinates relative to the fixed coordinates: This relationship only holds true when the moving coordinates move with a constant velocity vector (magnitude and direction) relative to the fixed coordinates. It is not true if the moving coordinates are accelerating !
