Answer:
69.66 Joule
Explanation:
mass of bicycle frame, mf = 8.29 kg
mass of wheel, mw = 0.820 kg
radius, r = 0.343 m
velocity, v = 3.6 m/s
There are two wheels in the bicycle.
There are two types of kinetic energy of the system one is kinetic energy of rotation and another is rotational kinetic energy.




K = 69.66 J
An influence upon an oscillatory system that has the effect of reducing/restriction or preventing its oscillations. Damping is produced by processes that dissipate the energy stored in the oscillation.
Answer:
when the gas cools it cools
Explanation:
I assume the 100 N force is a pulling force directed up the incline.
The net forces on the block acting parallel and perpendicular to the incline are
∑ F[para] = 100 N - F[friction] = 0
∑ F[perp] = F[normal] - mg cos(30°) = 0
The friction in this case is the maximum static friction - the block is held at rest by static friction, and a minimum 100 N force is required to get the block to start sliding up the incline.
Then
F[friction] = 100 N
F[normal] = mg cos(30°) = (10 kg) (9.8 m/s²) cos(30°) ≈ 84.9 N
If µ is the coefficient of static friction, then
F[friction] = µ F[normal]
⇒ µ = (100 N) / (84.9 N) ≈ 1.2
The IMA of the pulley shown is 2.
