Atorque of 50 n*m acts on a wheel of moment of inertia 25 kg*m^2 for 4 s and then is removed.
b)how many revolutions does it make in 15 s if it starts at rest?
i found the angular acceleration, 2 rad/s^2, but i don't know how to find the amount of revolutions.

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.
