A body is projected from the ground with the velocity \(98 \text{ m/s}\), making an angle of 30 degree with the horizontal.

Find:

(a) The time of flight

(b) Maximum height attended.

(c) The horizontal range of the body.

Let the solution of (a), (b), (c) be denoted as \(A,B,C\) respectively. Submit your answer as \(A\times(B+C) \).

**Details and Assumptions**:

- Take\( g=9.8 \text{ m/s}^2\).
