A weightlifter of mass M stands on a scale. He must lift a barbell of mass m over his head. The barbell begins at rest on the floor. The weightlifter squats to lift it up, lift the barbell and then stand up straight with the barbell waist high. After a pause he drops the barbell on the floor. Make a graph of reading on the scale versus time, making specific time during the lifting process. Defense and justify your graph. Make sure you communicate the assumptions you make about the speed/acceleration of the barbell in the lifting process. :grumpy:
