1. Cars A and B are moving toward each other in one dimension. A has a mass of 2.0 x 10³ kg and a velocity of 50 m/s, while B has a mass of 4.0 x 10° kg and a velocity of -20 m/s. They suffer a totally inelastic collision (the cars stick together and move as one object after colliding). (a) What is their common velocity after the collision? (b) What is the total kinetic energy lost during the collision?

Two cars collide at an intersection. Car A�, with a mass of 1900 kgkg , is going from west to east, while car B�, of mass 1300 kgkg , is going from north to south at 14.0 m/sm/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55.0 ∘∘ south of east from the point of impact.How fast were the enmeshed cars moving just after the collision?

A car (mass = 1110 kg) is traveling at 31.3 m/s when it collides head-on with a sport utility vehicle (mass = 2380 kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. At what speed was the sport utility vehicle traveling?

If a mass of 1 kg with an initial velocity of 4 m/s to the right collides elastically with a mass of 3 kg going 1 m/s to the left, what will be the velocity of the first mass after the collision? Right is positive, left is negative. Options include: + 1.0 m/s -2.5 m/s -1.5 m/s -3.5 m/s

Two toy cars with masses of 0.70 kg  and 0.30 kg, respectively, move towards each other and collide  head-on and then stick together.. The magnitude of the initial velocity for each of of the toy cars is 15.0 m/s. What is the speed of the toy cars  immediately after collision?

Blocks A and B are moving toward each other on a horizontal, frictionless surface. Block A has a mass of 5 kg and a velocity of +40 m/s, while B has a mass of 10 kg and a velocity of -6 m/s. They suffer a head on, completely inelastic collision. What is the common speed of the blocks after the collision.

Riding in some bumper cars, you (174 kg for you and car) moving to the right at 15.6 m/s and collide with your younger cousin (145 kg for cousin and car) who is moving to the left at 20.6 m/s. After the collision, you are moving at 9 m/s to the LEFT. What is the velocity of your cousin immediately after the collision?(a) 1.88 m/s to the RIGHT(b) 50.1 m/s to the LEFT(c) 8.92 m/s to the RIGHT(d) 50.1 m/s to the RIGHT(e) 7.43 m/s to the RIGHT

A block of mass m1 = 2 kg and speed v1 = 0.40 m/s collides with a block of mass m2 = 5 kg that is initially at rest. If the two blocks stick together, what is their speed right after the collision?

A 2.1-kg object moving in the positive x-direction at 5.2 m/s collides with a 1.7-kg object moving in the positive y-direction at 8 m/s. The two masses stick together after the collision. With what speed does this composite object move?
