A 110 kg football player runs forward at 8 m/s and plows into an 80 kg referee standing on the field causing the referee to fly forward at 5.0 m/s

Modify the equation fδt=δ (mv) to find the force of friction.

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.

Find the mass by adding the numbers from the three sliders
