# Lesson Worksheet: Angular Momentum in Terms of Linear Momentum Physics

In this worksheet, we will practice calculating the angular momentum of an object that is moving along a circular path from its instantaneous linear momentum.

**Q1: **

Which of the following is the correct unit of angular momentum?

- Akg⋅m
^{2}/s^{2} - Bkg⋅m
^{2}⋅s - Ckg⋅m
^{2}/s - Dkg
^{2}⋅m^{2}/s - Ekg⋅m/s

**Q2: **

The figure shows an object with a mass and an instantaneous linear velocity . At which of the labeled points would the angular momentum of the object be greatest?

- APoint A
- BPoint D
- CPoint B
- DPoint C
- EPoint E

**Q3: **

An object moves along a circular path. The object has a linear momentum of 12 kg⋅m/s
and an angular momentum of 57.6 kg⋅m^{2}/s. What is the radius of the object’s circular path?

**Q4: **

An object moves along a circular path with a radius of 12 m.
The object has a tangential speed of 4.4 m/s
and an angular momentum of 475.2 kg⋅m^{2}/s.
What is the mass of the object? Give your answer to the nearest
kilogram.

**Q5: **

The SI unit of angular momentum is kilogram meters squared per second
(kg⋅m^{2}/s). The SI unit of
linear momentum is kilogram-meter per second (kg⋅m/s). If angular momentum is divided by linear momentum, what will
the SI units of the resultant quantity be?

- As/m
- Bm
^{2} - C1/m
- Dm/s
- Em

**Q6: **

A brick is swung around in a circle on the end of a rope. The brick has a linear momentum of 3 kg⋅m/s, and the rope is 2 m long. What is the magnitude of the angular momentum of the brick?

**Q8: **

An object moves along a circular path.
The object has a mass of 15 kg,
a linear speed of 2.0 m/s,
and an angular momentum of 84 kg⋅m^{2}/s.
What is the radius of the object’s circular path?

**Q10: **

The SI unit of angular momentum is kilogram meters squared per second (kg⋅m^{2}/s).
If angular momentum is divided by a length,
what will the SI unit of the resultant quantity be?

- Akg⋅m
^{3}/s - Bkg/m⋅s
- Ckg⋅m/s
^{2} - Dkg⋅m/s
- Ekg⋅m
^{2}/s
