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 ...
The impulse momentum theorem adds time to both sides of this equation, to tell you force multiplied by time equals mass multiplied by the change of velocity when the force is applied. F*∆t = m*∆v.
