You work for the National Park Service testing a small cannon
used to prevent avalanches by shooting down snow overhanging the
sides of mountains. In order to determine the range of the cannon,
it is necessary to know the speed with which the projectile leaves
the cannon (muzzle speed), relative to the ground. The cannon you
are testing has a weight of 517 kg and shoots a 21-kg projectile.
During lab tests where the cannon is held and cannot move, the
muzzle speed is 269 m/s. You want to calculate the projectile's
muzzle speed with respect to the ground under field conditions when
the cannon is mounted so that it is free to move (recoil) when
fired. You take the case where the cannon is fired horizontally
using the same shells as in the laboratory.
What is the muzzle speed of the projectile when the cannon is free
to move?

You have an internship working for the National Park Service. They start you off in the laboratory which tests possible new equipment. Your first job is to test a small cannon used to prevent avalanches in populated areas by shooting down the velocity of the projectile as it leaves the cannon (muzzle speed) so that the range and trajectory of the cannon can be determined. heavy snow concentrations. You want to find out Lab, Initial Lab, Final The cannon you...
The cannon you are testing weighs 260 kg and shoots a 15 kg projectile. During the lab tests the cannon is held horizontal in a rigid support so that it cannot move. Under those conditions, you use video analysis of the projectile to determine that the muzzle speed is 300 m/s. When fired in the field, the cannon is not rigidly attached to the ground, but it is free to move (recoil) when it is fired. There are ropes attached...
Engr 135 Program #6 Spring 2019 Cannon Muzzle Velocity& Projectile Impact Point Part I- Cannon Muzzle Velocity We wish to determine the muzzle velocity of a physics lab spring "cannon." The cannon will be fired from a table top, with the cannon itself parallel to the floor. It is established that the height of the bottom of the ball, just as it is leaving the cannon, is Yo in meters. We assume that for the short distances and velocities involved,...
