Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Let the initial angle of inclination is θ so the initial velocity vector will be,
This can also be written in the coordinate form as,
Calculation:
Given: v = 10 m/s
- At a subsequent instant, it is moving at the same rate in a direction inclined at 30° to the former direction.
So, the final angle of inclination will be (θ -30°) so the final velocity vector will be,
So, change in the velocity,
Using trigonometric formulas,
