The total momentum of two marbles is .05 kg x m/s before they collide. No outside forces interfere with the marbles. What is the momentum of the marbles after the collision?

0.05 m/s (It normally stays the same if no outside forces interferes)

Explanation:

It is 0.05 because of you pay attention to the info, it will say that the momentum ”before” the 2 marbles collision is 0.05 m/s, so it is still 0.05 m/s.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
