Interactive LearningWare 8.1 reviews the approach that is necessary for solving problems such as this one. A motorcyclist is tra

veling along a road and accelerates for 4.36 s to pass another cyclist. The angular acceleration of each wheel is 6.10 rad/s2, and, just after passing, the angular velocity of each is 75.2 rad/s, where the plus signs indicate counterclockwise directions. What is the angular displacement of each wheel during this time?

Answer:

The angular displacement of each wheel is 269.92 rad

Explanation:

Given:

Angular acceleration \alpha = 6.10 \frac{rad}{s^{2} }

Time to pass cyclist t = 4.36 s

Angular velocity \omega _{f} = 75.2 \frac{rad}{s}

According to the equation of kinematics,

  \omega _{f} = \omega _{i} + \alpha   t

   \omega _{i} = \omega _{f} - \alpha   t

   \omega _{i} = 75.2 - 6.10 \times 4.36

  \omega _{f} = 48.60 \frac{rad}{s}

For finding angular displacement,

    \omega _{f} ^{2}  - \omega _{i} ^{2}  = 2 \alpha  \theta

Where \theta = angular displacement,

  \theta  = \frac{\omega _{f}^{2} - \omega _{i} ^{2}  }{2\alpha }

  \theta  = \frac{5655.04 - 2361.96  }{2\times 6.10 }

  \theta = 269.92 rad

Therefore, the angular displacement of each wheel is 269.92 rad

Why is the perfect mechine is not possible in the real life?​
Vinvika [58]

Answer:

Because the mechanical advantage of the machine is affected by friction and weight but velocity ratio is not. So, mechanical advantage is less than velocity rate. Thus, the machine's efficiency is less than 100% and can't be a perfect machine

A rubber-wheeled 50 kg cart rolls down a 35 degree concrete incline. Coefficient of rolling friction between rubber and concrete
lapo4ka [179]

Answer:

(a) 5.62 m/s²

(b) 5.46 m/s²

Explanation:

The given values are:

mass,

m = 50 kg

angle

= 35°

(a)

If friction neglected,

⇒ F_x=mgSin \theta=ma

⇒ a_x=gSin \theta

       =9.8 \ Sin35^{\circ}

       =5.62 \ m/s^2

(b)

If friction present,

⇒ F_x=mgCos \theta

⇒ F_x=mgSin \theta-\mu_r mgCos \theta

⇒ a=gSin \theta-\mu_rgCos \theta

      =9.8 \ Sin35^{\circ}-0.02\times 9.8 \ Cos30^{\circ}

      =5.46 \ m/s^2
