A shell is shot with an initial velocity of 25 m/s, at an angle of = 57° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that air drag is negligible?
A small cannonball with mass 9 kilograms is shot vertically upward with an initial velocity of 190 meters per second. If the air resistance is assumed to be directly proportional to the speed of the cannonball, a differential equation modeling the projectile velocity is du т = mg – kv dt Assume that k = 0.0025, and use g = - 10 meters/second2. Solve the differential equation for the velocity v(t). Don't forget to include the initial condition. v(t) =...
