he 2.5 mg car as shown in is figure 6-50 being towed by a winch. if the winch exerts a force of
t = (225s) n on the cable, where s is the displacement of the car in meters, determine the
velocity of the car when s = 10 m, starting from rest. neglect rolling resistance of the car.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
