Practice with Impulse Pattern with "A" value Mathematical Model Data Table Form Graph Form 1. -Force of Impact vs time of impact -- A 4 kg mass is dropped and hits a force plate at 2.5 m/s. Different layers of foam change the time that it takes to stop. Force = mxv/t-10/t t(_) 0.1 0.2 0.5 Force MAR 22 + F(____) Time (@ 2. --Impulse vs change in velocity -- A 2 kg mass is dropped from various heights reaching different peak velocities before coming to rest when striking a force plate. tve Impulse = Av(_____) 1 Impulse 2 5 2v Aa A |(_________) Change in Velocity D
