After fixing a flat tire on a bicycle you give the wheel a spin. If its initial angular speed was 6.36 rad/s and it rotated 14.7
lesya692 [45]

To solve this problem we will apply the concepts related to the cinematic equations of angular motion. On these equations, angular acceleration is defined as the squared difference of angular velocity over twice the radial displacement. This is mathematically:

\alpha = \frac{\omega^2-\omega_0^2}{2\theta}

Our values are,

\text{Initial angular velocity} = \omega_0 =6.36 rad/s

\text{Final angular velocity} =  \omega =0

\text{Angular displacement} =  \theta = 14.7rev = 29.4\pi rad

Replacing,

\alpha = \frac{- 6.36^2}{29.4\pi}

\alpha = -0.43rad/s^2

Therefore the angular acceleration is -0.43rad/s^2

I’m not accelerating, so the net (vertical) force on me, while I’m sitting here doing this lab is _________
Elina [12.6K]

Answer:

Net force is zero

Explanation:

According to the Newton's second law, the net force on the body is equal to the product of mas of body and the acceleration.

here acceleration is equal to zero so net force is also zero because mass of an object can never be zero.
