    Angle of a trajectory required to make it go a specified distance?

    Here is the problem at hand: A gun has a muzzle speed of 100 meters per second. What angle of elevation should be used to hit an object 180 meters away? Neglect air resistance and use g = 9.8 m / sec^2 as the acceleration of gravity. I attempted to solve this by calculating the time...

    Angular Speed Between 2 rims attached by a belt

    So I'm new to the Physics Forums and am looking for some help on this problem: Wheel A of radius r=10cm is coupled by belt B to wheel C with radius R=25cm. the angular speed of wheel A is increased from rest at a constant rate of 1.6 rad/s^2. Find the time needed for wheel C to reach an...
