A person is standing on a weighing machine placed on the floor of an elevator. The elevator starts going up with some acceleration, moves with uniform velocity for a while and finally decelerates to stop. The maximum and the minimum weights recorded are 72 kg and 60 kg. Assuming that the magnitudes of the acceleration and the deceleration are the same., find a. the true weight of the person and b. the magnitude of the acceleration. Take g=9.9 m/s^2 .

A train starts from rest and moves with uniform acceleration alpha for some time and acquires a velocity v it then moves with constant velocity for some time and then decelerates at rate beta and finally comes to rest at the next station. If L is distance between two stations then total time of travel is
