2, When you divide the total distance and total time for a trip, you calculate a(n) average acceleration instantaneous speed average speed non-uniform speed constant speed 3. A heavy object and a light object are dropped from rest at the same time in a vacuum. The heavier object will reach the ground It depends on the shape of the object at the same time as the lighter object It depends on the mass of the object after the lighter object...

Relative Velocity vs. Time Graph Ranking Task Rank car #1's speed relative to the ground at the lettered times (A through E). Constants Rank from largest to smalest. To rank Items as equivalent, overlap them. Two cars travel on the parallel lanes of a two-lane road. The cars are at the same location at time t 0s, and move in such a way as to produce the velocity (relative to the ground) vs. time graph shown in (Figure 1). On...
