15. A 10000Kg car is moving toward north at a speed of 3m/s at noon. One hour later, the car is moving toward east at 4m/s. The change in momentum of the car during that onehour period is (a) 10000Kgm/s, toward east. (b) 50000Kgm/s, toward 37 degrees north of east. (c) 50000Kgm/s, toward 53 degrees north of east. (d) 50000Kgm/s, toward 37 degrees south of east.. (e) 50000Kgm/s, toward 53 degrees south of cast.

What is the momentum in kg · m/s of a garbage truck that is 1.20 ✕ 104 kg and is moving at 35.0 m/s? At what speed in m/s would an 8.00 kg trash can have the same momentum as the truck?

a) What is the total momentum of this two-astroid system? (Give answer in component form). Don’t forget to include appropriate units in your answers!

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? +y m2) V4 30 m m2 +X +X 45° (a) (b) Fig. 2: Collision of mass m, and m, 8. Figure 2b shows that, after a collision, m, travels at a speed v3 at an angle e, = 315.0° with respect to the horizontal axis, while m, moves at a speed v, at an angle O, = 30.0° with respect to the horizontal axis. Write an equation for the system's total momentum in the x and y direction after the collision. 9. Using the equations produced in question 8, solve the value of v3 and v4.
