A Revolutionary War cannon, with a mass of 2020 kg, fires a 20 kg ball horizontally. The cannonball has a speed of 139 m/s after it has left the barrel. The cannon carriage is on a flat platform and is free to roll horizontally. What is the speed of the cannon immediately after it was fired?

Answer in units of m/s.

The cannon, which has a mass of 2020 kg and discharges a ball weighing 20 kg horizontally, moves at a speed of 1.27 m/s right after the shot. Following its exit from the barrel, the cannonball moves at a speed of 139 m/s.

m1: Cannon mass, 2260 kg

v1 denotes the cannon's speed.

the ball's velocity is 105 m/s, and its mass is 21 kg.

We have m1v1=m2v2, v1=20*139/2020, and v1=1.27 m/s due to the system's preserved momentum.

The cannon travels at 1.27 meters per second.

How do you determine a system's total momentum for an object?

Add together the individual momentums of the two objects in a collision to get the total momentum. If p represents momentum, m is mass, and v is velocity, then the equation p=mv can be used to calculate a method for calculating the individual objects' respective velocities.
