Question
If P (q) and Q are two points on the ellipse , then locus of the mid – point of PQ is



 none of these
Hint:
Equation of ellipse =
The correct answer is:
Coordinate of Point P() = (a cos , b sin)
Coordinate of Point Q () = ( a cos() , )
Coordinate of Point Q () = ( a sin() , )
Let R be the midpoint of P and Q and coordinates of R = (h, k)
comparing with equation of ellipse i.e.

An object moves in a straight line. It starts from the rest and its acceleration is . 2 ms^{2}.After reaching a certain point it comes back to the original point. In this movement its acceleration is 3 ms^{2}, till it comes to rest. The total time taken for the movement is 5 second. Calculate the maximum velocity.
