Impulse-momentum can be used to calculate the average force on the ball. \(F = -72.5N \,\) (value is negative as moving to the left) The negative sign in front of the \(-72.5N\) indicates that the ...

An object being fired from a cannon is also a collision where momentum must be conserved. As the momentum before the 'collision' is zero, the momentum after the collision is zero. In physics ...
