Answer:
58.0
Explanation:
if you take 2/5 of 58.0 you get 23.2
Answer:
8.0 rad/s
Explanation:
I₁ = 1.0 kgm², ω₁ = -20.0 rad/s (clockwise is positive direction)
I₂ = 4.0 kgm², ω₂ = 15.0 rad/s
Angular momentum conservation:
I₁ω₁ + I₂ω₂ = (I₁ + I₂)ω
1.0 x (-20.0) + 4.0 * 15.0 = (1.0 + 4.0)ω
40.0 = 5.0ω
so ω = 8.0 rad/s
You can do this all in one Step
Formula
F2/F1 = 8.5/(25r^2) // 1 / r^2
Solution
The "ks, r^2 and q1 q2" all cancel out
You are left with 8.5/25 as the ratio
- F1 = 5.7 N
- F2 = 8.5 / 25 * F1
- F2 = 8.5 / 25 * 5.7
- F2 = 1.938

Answer:
Friction is the resistance to motion created by two objects moving against each other. Friction creates heat. Unless acted on by a force, objects in motion tend to stay in motion and objects at rest remain at rest.
