Graph between the square of velocity (v) of a particle and the distance (s) moved is shown in figure. The acceleration of the particle in kilometers per hour square is:
2250
3084
-2250
-3084
As learnt in
3rd equation or Velocity –displacement equation -
Final Velocity
Displacement
Initial velocity
acceleration
-
We use V2 = u2 + 2as
V2 - u2 = 2as
After solving we get acceleration of particle -3084
Option 1)
2250
This answer is incorrect
Option 2)
3084
This answer is incorrect
Option 3)
-2250
This answer is incorrect
Option 4)
-3084
This answer is correct
