Find what weight does the man read on the scale

Reference no: EM13670937

An 80 kilogram man is standing in an elevator on a "bathroom scale" which reads weight. The elevator is moving downward at a speed of 3 m/s. During a 2 sec period the elevator slows down and stops. During these 2 sec, find what weight does the man read on the scale?
