(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
