Start with the equation:

Plug in what you know, and solve:

Find matching soluation:
C.) 1.5 kg
L = r x p = rmv = mr²ω
L = 0.25 x 0.75² x 12.5 = 1.758
Explanation:
Light Light from a moving source travels at 300,000 km/sec (186,000 miles/sec).
Note:
The Speed of Light Is Constant.
Answer:
Explanation:
Use the following equation:
and solve for F:
and filling in:

F = 4.0 ×
N
Answer: 0.031rad/s
Explanation:
Tangential speed = 50.0m/s
Diameter = 3200m
Radius = diameter/2
= 3200/2 = 1600m
Angular speed = tangential speed / radius
= 50/1600
= 0.031rad/s
