A bicycle is traveling north at 5.0 m/s. The mass of the wheel, 2.0 kg, is uniformly distributed along the rim, which has a radi
andreev551 [17]

Answer:2

Explanation:

Given

Velocity of bicycle is 5 m/s towards north

radius of rim r=20 cm

mass of rim m=2 kg

Angular momentum \vec{L}=I\cdot \vec{\omega }

I=mr^2=2\times 0.2^2=0.08 kg-m^2

\omega =\frac{v}{r}=\frac{5}{0.2}=25 rad/s

L=0.08\times 25=2kg-m^2/s  

direction of Angular momentum will be towards west

A rubber band has potential energy of 5 J. If the spring constant of the rubber band is 50 N/m, what is the displacement of the
Valentin [98]
To determine the displacement, since we are given the potential energy, we use the equation for potential energy. For a spring, it is one-half the product of the spring constant and the square of the displacement. We do as follows:

PE = kx^2/2
5 Nm = 50N/m (x^2)
x = 0.32 m

Therefore, the displacement would be 0.32 m.

A solid sphere and a solid cylinder , both uniform and having the same mass and radius, are released from rest at the same heigh
IRISSAK [1]

Answer:

I (cylinder) = 1/2 M R^2

I (sphere) = 2/5 M R^2

The equation  of motion shows

I * alpha = M g R sin theta = const

An increase in the moment of inertia will result in a smaller acceleration

The cylinder will have the smallest forward velocity because it will arrive at the bottom after the sphere
