SUMMARY

The discussion centers on calculating the angle of elevation required for a projectile to hit a target 180 meters away, given a muzzle speed of 100 meters per second and neglecting air resistance with a gravitational acceleration of 9.8 m/s². The user expresses confusion over the calculations involving time and height. A suggestion is made to share the user's calculations for more targeted assistance.

PREREQUISITES
  • Understanding of projectile motion principles

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 required for the ball to travel the distance and then correlating that with the height to equal zero at that time..but honestly I'm just plain lost on this one, so any help would be great!
