Given that the diameter of the wheel is d = 35 m.

Also, given that it completes 1 rev in 2 min 20 sec.

We have to find angular velocity, tangential velocity and centripetal acceleration.

The radius of the wheel will be

$\begin{gathered} r\text{ =}\frac{d}{2} \\ =\frac{35}{2} \\ =17.5\text{ m} \end{gathered}$

The tangential velocity is

$\begin{gathered} v=\frac{2\pi r}{t} \\ =\frac{2\times3.14\times17.5}{2\times60+20} \\ =0.785\text{ m/s} \end{gathered}$

The angular velocity will be

$\begin{gathered} \omega=\frac{v}{r} \\ =\frac{0.785}{17.5} \\ =0.044\text{ rad/s} \end{gathered}$

The centripetal acceleration is

$\begin{gathered} a_c=\frac{v^2}{r} \\ =\frac{(0.785)^2}{17.5} \\ =0.035m/s^2 \end{gathered}$

Two of the angles in a triangle are complementary. The third angle is twice the measure of one of the complementary angles. What

Marrrta [24]

Explanation:

Let the 2 be X and Y.

Z is 3rd angle.

Z=2X

w.k.t Sum of angles in a triangle is 180°

Z+X+Y=180°

2X+90°=180°

2X=90°

=>X=45°

=>Y=90°-45°=45°

=>Z=2X=2(45°)=90°

Hope this helps you.
