The lock down has made mellisa soft. She gets
caught the last time she tries to steal a box of red
vines, so mallisa decides she needs to start
working out. Since gyms are so expensive, mallisa
decides to practice pushing a 100 kg box filled
with chemistry textbooks place of red vines)
across her living room and back, a distance of 30
m. If mellisa pushes with a force of 875 N at an
angle 25 degrees below the horizontal, what was
the amount of work that mellisa performed on the
box?
a)-23.800J
b) -13,600J
c)31,200J

- To get in shape, you head to the local gym to exercise by lifting weights. Using a lat machine (Fig. P5.48), you notice that the wire connected to the bar is run around three different pulleys and is connected to a vertical stack of weights on the other end. The weights move up and down as you pull down on the bar. Suppose you set the machine so that the weight to be lifted is 120.0 lb. When you pull down on the bar, exerting a constant force, the acceleration experienced by the weights is 0.250 m/s2. What tension must exist in the wire connecting the bar and weights under these conditions? Assume the pulleys are massless and frictionless.
