An M777 155mm howitzer fires at Yuma Proving Ground's Kofa Firing Range. (Chuck Wullenjohn/U.S. Army) HUNTSVILLE, Ala. — The U.S. Army is slated to begin evaluating a hypervelocity projectile for the ...

In the problem, we want to find the best angle (θ) for Tarzan to let go of the rope in order to get the maximum range. What makes this tricky is that the later he lets go of the rope, the better the ...

In a previous post, I was trying to show that the range of a projectile depends on the launch angle. Yes, this isn't that too difficult to see in an introductory physics course, but how do you show ...
