Unformatted text preview: (definition of law of conservation of momentum) To find the force of the person, I used the definition of force which is that force is the exchange of momentum with respect to time. So to find force, I knew I had to find the change in momentum/change in time. Since momentum = mass x velocity, to find the change of momentum I would find mass(final velocity initial velocity). The mass of the person = m, the final velocity = 0 and the initial velocity = V0, so the change in momentum = m(V0). The time given in the problem is t0, so the force of the person = m(V0)/t0 Force = change in momentum/change in time Change in momentum = mass(V final V initial ) = m(0V0) = m(V0) Mass = m V final = 0 V initial = V0 Change in time = t0 Force = m(V0)/t0 http://galileoandeinstein.physics.virginia.edu/lectures/momentum.html (definition of force/equation)...
