Assume that an arrow that consists of a mass of around 0.420 kg is traveling horizontally then it strikes a 1.75 kg target that has been positioned on a horizontal surface. Assume that the arrow ends up embedded in the target and the target then slides across the horizontal surface having friction. The target then travels a distance of 7.6 m before it lastly comes to rest. Therefore, if the coefficient of kinetic friction is then 0.15, then what would have been the speed of the arrow just before it strikes the target?
