9. In drag racing, acceleration is more important than speed, and therefore drag
racers are designed to provide high accelerations. Suppose a drag racer has a
mass of 1,250 kg and accelerates at a constant rate of 16.5 m/s. How large is
the unbalanced force acting on the racer?

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 earthβmoon (center-to-center) distance is 3.82 Γ 10^8 m, earth's radius is 6.37 Γ 10^6 m, moon's mass is 7.36 Γ 10^22 kg, and earth's mass is 5.98 Γ 10^24 kg.
