SUMMARY
The change in momentum of a 4.5 kg object projected at a 53° angle and hitting the ground after 3.6 seconds can be calculated using the formula P = mv. To find the final velocity, kinematic equations must be applied, considering the time of flight and the angle of projection. The absence of air resistance simplifies the calculations, allowing for a direct application of physics principles to determine momentum change.
