Two cars of equal mass, one traveling east and the other traveling west, undergo a head-on collision. Both cars are traveling at a constant velocity before the collision; however, the car traveling east accelerated twice as fast as the car traveling west before reaching its constant speed. Is total momentum just before the collision equal to the total momentum just after the collision? (You may consider the net external force on the system is zero). O No, since the objects accelerated to their constant velocity before the collision, the requirement of a system having no acceleration for conservation of linear momentum is not met. Yes, at the time of the collision, there is no external force acting on the system, which satisfies the requirement of conservation of linear momentum. O No, the cars had different momentums leading up to the collision. O Yes, at the time of the collision, both cars have the same mass and were traveling at the same speed, making their momentum equal before the collision and after the collision.

() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg. Before the collision, blocks mą and mg are stationary and the spring is relaxed. m2 Frictionless - For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move) • For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any force acts on mg and cause it to move)…

A car of mass m_auto = 1.20x10^3 kg travels west-east at a speed of 50.0 km/h, while a wagon of mass m_ wagon = 2.80x10^3 kg travels at a speed of 40.0 km/h in a south-north direction; vehicles collide at an intersection (Point A). From the above and assuming that the crash that occurred is considered a perfectly inelastic collision, determine the magnitude and direction of the velocity that will occur after the collision.
