9. a 0.500 kg ball with a speed of 4.0 m/s strikes a stationary 1.0 kg target. the ball and target

stick together. if momentum is conserved, what is the total momentum of the ball and target
after the collision?
a. 0.0 kgm/s
b. 0.5 kgm/s
c. 1.0 kgm/s
d.2.0 kgm/s

D. 2.0 kg m/s

Explanation:

Momentum after = momentum before

p = (0.500 kg) (4.0 m/s) + (1.0 kg) (0 m/s)

p = 2.0 kg m/s

Sample Response: Nonvascular plants have no vascular tissue and lack true roots, stems, and leaves. As a result, they must live in moist places to absorb water and nutrients directly from the surrounding environment. They also grow much smaller because they must transfer nutrients from cell to cell. Seedless vascular plants have vascular tissue, so they can live farther away from water and grow much larger. Seedless vascular plants also have true roots, stems, and leaves.
