Q. Two particles P and Q simultaneously start moving from point A with velocities 15m/s and 20 m/s respectively. The two particles move with accelerations equal in magnitude but opposite in direction. When P overtakes Q at B then Its velocity is 30m/s. The velocity of Q at point B will be

Motion in a Straight Line

Solution:

For P , 30 = 15 + at
For Q , v = 20 - at
