A 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell How large is the NET vertical force acting on the barbell?
If a 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell, the NET vertical force acting on the barbell is 1000 N. It does not matter how heavy the weightlifter or the barbell might be.
Calculate the work done in lifting a 500-N barbell 2.2m above the floor what is the potential energy of the barbell when it is lifted to this height?
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)

Which joint comes into use when you lift your head?
It would depend entirely on the type of lift, but in most cases the humeroulnar joint, or the elbow, would most likely be involved, e.g. barbell rows and presses, and inevitably in a commercial gym, the barbell curl. The elbows do not contribute to the movement of the deadlift or power clean, in the former staying locked throughout, the latter only moving to rack the bar on the deltoids after the force against the bar ceases at the top of the movement.
