Example Projectile Motion Problems
Physics Phun!
| a) A mortar shell projected at an angle of 65o above the horizontal strikes a tower 25 m away at a point 15 m above the point of projection. Find the initial speed v0 of the projectile. |
 |
| b) How long was it in the air? |
 |
| c) Find the magnitude and direction of the velocity of the projectile when it strikes the tower. |
 |
| d) Find the maximum height of the projectile. |
 |
| e) If the projectile had not struck the tower, what would have been the range R of the projectile? |
 |
f) What would be the magnitude and direction of the velocity of the projectile upon impact?
|
 |
| An antiaircraft artillery gun fires a projectile with a muzzle velocity of 1000 m/s. If the projectile is to explode at an altitude of 4000 m and a horizontal range of 3000 m from the gun site, find the angle of elevation of the gun and the fuse setting of the projectile. |
 |
| Find the firing angle. |
 |
| Find the time until detonation. |
