A gun is shot with initial velocity 120 m/s at a 30 degree angle to the horizontal how far horizontally from the gun does the bullet land?

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
