An 20-cm-long bicycle crank arm, with a pedal at one end, is attached to a 25-cm-diameter sprocket, the toothed disk around whic
Andrej [43]

Answer:

0.033815 m/s²

12.48810875 m

Explanation:

t = Time taken = 12 s

\omega_f = Final angular velocity = 95 rpm

\omega_i = Initial angular velocity = 64 rpm

\alpha = Angular acceleration

\theta = Angle of rotation

\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\frac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\frac{95\times \frac{2\pi}{60}-64\times \frac{2\pi}{60}}{12}\\\Rightarrow \alpha=0.27052\ rad/s^2

Tangential acceleration is given by

a_t=\alpha r\\\Rightarrow a_t=0.27052\times 0.125\\\Rightarrow a_t=0.033815\ m/s^2

The tangential acceleration of the pedal is 0.033815 m/s²

\omega_f^2-\omega_i^2=2\alpha \theta\\\Rightarrow \theta=\frac{\omega_f^2-\omega_i^2^2}{2\alpha}\\\Rightarrow \theta=\frac{\left(95\times\frac{2\pi }{60}\right)^2-\left(64\times\frac{2\pi}{60}\right)^2}{2\times 0.27052}\\\Rightarrow \theta=99.90487\ rad

Linear displacement would be 99.90487\times \frac{1}{2\pi}\times 2\pi\times 0.125=12.48810875\ m

Length of chain that passes in the interval is 12.48810875 m

A 16.9 kg monkey is swinging on a
mrs_skeptik [129]

The potential energy of the monkey at the given position is 600.9 J.

<h3>What is potential energy?</h3>

Potential energy is the energy stored in a body that depends upon the relative position of various parts of the body.

It increases with increase in the height of the object above the ground level.

<h3>Potential energy of the monkey</h3>

The potential energy of the monkey is calculated as follows;

P.E = mgh

P.E = mg (L sin43)

where;

  • m is mass of the monkey, given as 16.9 kg
  • g is acceleration due to gravity, given as 9.8 m/s²
  • L is length of the vine given as 5.32 m

Substitute the given parameters and solve potential energy of the monkey

P.E = (16.9)(9.8)( 5.32 x sin 43)

P.E = 600.9 J

Thus, the potential energy of the monkey at the given position is 600.9 J.
