A weightlifter lifts a 1400 N barbell 2.5 meters. Calculate the work done during the lift

W = 3500 J

Explanation: Work is the product of the amount of force and the perpendicular distance or W = Fd.

W = Fd

   = 1400 N ( 2.5 m )

   = 3500 J

the answer for apex is the lowest

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
