7. A 1.000 kg particle moves at a speed of 0.500 m/s, as shown in Figure 2a. It collides with a 2,000 kg particle at rest at origin. What is the system's total momentum of the system in the x and y direction before the collision? (m2) V. 30 m. m2 +X 45° m (a) (b) Fig. 2: Collision of mass m, and m2

What is the momentum in kg · m/s of a garbage truck that is 1.10 ✕ 104 kg and is moving at 28.0 m/s? kg · m/s (b) At what speed in m/s would an 8.00 kg trash can have the same momentum as the truck? m/s

Situation 7. A ball of mass 0.220 kg that is moving with a speed of collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.8m/s.    C. Supposed that a ball is dropped from a height of 2.60 m. If the coefficient of restitution between the ball and the ground is 0.60, to what height will it bounce?

A firecracker breaks up into several pieces, one of which has a mass of 200 g and flies off along the x-axis with a speed of 82.0 m/s. A second piece has a mass of 300 g and flies off along the y-axis with a speed of 45.0 m/s. What are the magnitude and direction of the total momentum of these two pieces? O 361 kg m/s at 56.3° from the x-axis O 21.2 kg • m/s at 56.3° from the x-axis O 361 kg m/s at 0.983° from the x-axis ● 21.2 kg • m/s at 39.5° from the x-axis O 93.5 kg • m/s at 28.8° from the x-axis

A railroad car of mass 2.45 × 10* kg moving at 2.65 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? m/s (b) How much kinetic energy is lost in the collision? J

Problem B) An inelastic collision occurs between a particle of mass 1.5 kg moving with an initial velocity of v = (-2i – 1.33 + 0.7k) m/s and another particle of mass 0.8 kg that has an initial velocity of v = (5.6å + 0.53 + 4.3k) m/s. What is the final velocity of the particles in unit vector notation? %3D

This amazing summer adventure is finally winding down with some pool. Unfortunately, this pool table is wonky and some of the balls are larger than the others! Anthony hits the cue ball (mass = 0.15 kg) and it moves at 5 m/s when it strikes head on into the number 3 ball (mass = 0.30 kg). After this inelastic collision, the cue ball moves off at 60 degrees relative to the +x axis and the number 3 ball moves off at -30 degrees relative to the +axis as shown. What were the speeds of the two balls after the collision?
