Given Conditions:
- Initial velocity (V1) and Final velocity (V2) of the particle
- Distance between points A and B is 'd'
- Acceleration is proportional to velocity
Calculating Time taken from A to B:
- Let the time taken by the particle to travel from A to B be 't' seconds
- Given that acceleration is proportional to velocity, we have a = kV, where 'k' is a constant
- Using the kinematic equation, V = V1 + at, we can express acceleration 'a' as a = (V2 - V1) / t
- Substituting the value of acceleration 'a' as kV in the above equation, we get V = V1 + kVt
- Solving for 't', we get t = (V - V1) / (kV)
Explaining the Time Calculation:
- Initially, the particle moves from point A with an initial velocity V1
- As the particle moves towards point B, its velocity changes from V1 to V2 due to acceleration
- The time taken to cover the distance 'd' can be calculated using the above derived formula
- This time calculation is crucial in determining the motion of the particle along a straight line path
Conclusion:
- By understanding the relationship between acceleration and velocity, we can calculate the time taken by the particle to travel from point A to point B
- This analysis helps in studying the motion of particles under varying acceleration conditions along a straight line path.
