Question

The coordinates of a moving particle at any time t are given byand.The speed of the particle at time t is given by    [AIEEE 2003]a)b)c)d)Correct answer is 'B'. Can you explain this answer?

Answer

Answer

Answer

A3t+ B3t

Answer

Bring alpha to left hand side and differentiate on both sides

and same for 2nd equation.we will get vx and vy.thus find results we will get answers.
