Webthe total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects. The reason padded dashboards are used in cars is that they. increase the time of impact in a collision. Momentum of a system is conserved only when. there is no net external force acting on the system. Webmomentum = mass x velocity A moving object has... a. momentumb. energy c. speedd. all of the above d. all of the above When the speed of an object is doubled, its momentum... a. remains unchanged in accord with the conservation of momentumb. doublesc. quadruplesd. decreases b. doubles Impulse equations force x time

WebIn this case the momentum of the first ball is completely transferred to the three ball. Car A rear ends Car B, which has twice the mass of A, on an icy road at a speed low enough … WebTerms in this set (4) Car A has twice the mass of Car B; both travel at the same speed. Compared to Car B, Car A has: twice the energy More damage is done and more life is endangered in a head-on collision of two cars, each traveling at 30 mph, than in a car crashing into a brick wall at 30 mph because: media one radio group jamestown ny
