Question

Car can move from rest to 45 m/s in 3.0 seconds. It's acceleration is _________.

Answer 1

v – = v 0 + v 2

Step-by-step explanation:

The equation v – = v 0 + v 2 v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – v – is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate
