Question

26. Velocity of a body is 4 m/s and 10 m/s at time 1 and 3 second respectively. Find initial velocity
and acceleration, if acceleration is constant.

Answer 1

Explanation:

The equation –v=v0+v2 reflects the fact that when acceleration is constant, –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
