In this problem we will consider the collision of two cars initially moving at right angles. Weassume that after the collision the cars stick together and travel off as a single unit. The collisionis therefore completely inelastic. As shown below, two cars collide. Car one has an initial massand velocity of m1 = 1,140 kg, and v1 = 15.2 m/s. Car two has a mass of m2= 1,570 kg and aninitial velocity of v2 = 22.4 m/s. Find the magnitude and direction of the final two car system'smomentum.Car 1m2+ECar 2Figure 2.

A 100-g bat collides with a stationary 1.2 kg teddy bear. Immediately after the collision, the bat is traveling at an angle of 55 degrees from its original path. The bear is traveling in a direction 35 degrees from the original path of the bat. (All the motion occurs in two dimensions). If the bear is moving at 0.060 m/s immediately after the collision, how fast is the bat moving after the collision?

A soccer ball of 4.40925 (2 kilosg) pounds moves to the right a speed of 0.5 m/s. Hits a 0.1102311 (0.05 kilosg) pounds tennis ball initially moving to the left at 2 m/s.

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 billiard player sends the cue ball toward a group of three balls that are initially at rest and in contact with one another. After the cue ball strikes the group, the four balls scatter, each traveling in a different direction with different speeds as shown in the figure below. If each ball has the same mass, 0.16 kg, determine the total momentum of the system consisting of the four balls immediately after the collision. (Assume v1 = 0.33 m/s, ?1 = 70°, v2 = 0.49 m/s, ?2 = 30°, v3 = 0.23 m/s, v4 = 0.48 m/s.)

Two identical pucks collide on an air hockey table. One puck starts at rest. The incoming puck has a speed of 6.00 m/s and scatters to an angle of 30.0º. Use the fact that Θ1 – Θ2 = 90º for elastic collisions of objects that have identical masses — in other words, the pucks move apart at a right angle. (a) Sketch the collision, with angles labeled.
