Question

1. Calculate the momentum of a 1.0 kg object moving with a velocity of +20 m/s.

2. What is the velocity of an object that has a momentum of -30 kg m/s and a mass of 3.0 kg?

3. Two objects have equal momentum but one has four times the mass of the other. What is the relationship between
their velocities?

4. Which answer below shows the correct units for momentum?
A. kg m/s
B. kg m/s?
C. kg m/s
D. kg s/m
5. Two bowling balls each have a mass of 4.0 kg
The red Bar is moving east 2.0 m/s. The blue ball is moving west at 1.0 m/s. Calculate the total momentum of the system.

Answer 1

1)1*20=20

2)-30/3=- -10

3)velocity of the object 1=v1=4*V2

4) kg m/ s

5) momentum of the system= 12 kg m/ s
