Question
1. the distance covered by a body in each second exceeds the distance covered by it in the previous second by a. If it covers a distance a/2 in first second from start, total distance covered in first t seconds of the motion is
sir please explain me the formula you will use to solve this!!!
2. Two forces (p+q) and (p-q) make an angle 2β with one another and their resultant makes an angle α with the bisector of the angle between them. Then the value of p ⁄ q is
Sir the answer is 2tanβ ⁄ tanα.
