Question
A body of 2 kg has an initial speed 5ms–1. A force acts on it for some time in the direction of motion. The force time graph is shown in figure. The final speed of the body.
-
-
- 14.25 ms–1
- 4.25 ms–1
The correct answer is: 14.25 ms–1
Impulse = Change in momentum (i)
1 Again impulse = Area between the graph and time axis
...(ii)
From (i) and (ii),
