A small rubber wheel drives the rotation of a larger pottery wheel by running along its edge. The small wheel radius is 1.2 cm,

and it accelerates at 3 rad/s2. The pottery wheel has a radius of 36 cm. What is the angular acceleration of the pottery wheel? How long till the pottery wheel rotates at 60 rpm?

Answer:

α₂= 0.1  rad/s²

t= 62.8 s

Explanation:

Given that

For small wheel

r₁= 1.2 cm

α₁ = 3 rad/s²

For large wheel

r₂= 36 cm

Angular acceleration = α₂  rad/s²

The tangential acceleration for the both wheel will be same

a = α₁ r₁=α₂ r₂

Now by putting the values in the above equation

α₁ r₁=α₂ r₂

3 x 1.2 = 36 x α₂

α₂= 0.1  rad/s²

Given that

N = 60 rpm

Angular speed in rad/s ω

\omega = \dfrac{2\pi N}{60}

\omega = \dfrac{2\pi \times 60}{60}

ω = 6.28 rad/s

Time taken is t

ω = α₂ t

6.28 = 0.1 t

t= 62.8 s

Find the acceleration of an object that has a mass of 6 kg, if it is acted upon by a net force of 42 N.
pychu [463]

Answer:

7 m/s²

Explanation:

The formula for force is:

f= m*a

We want to find acceleration, so we must rearrange the formula for a. Divide both sides of the equation by m

\frac{f}{m}=\frac{m*a}{m}

\frac{f}{m}=a

Acceleration can be found by dividing the force by the mass.

The force is 42 newtons and the mass is 6 kilograms. A newton is equal to 1 kg * m/s², therefore the force is 42 kg* m/s².

f= 42 kg*m/s^2\\m=6 kg

Substitute the values into the formula.

a=\frac{f}{m}

a=\frac{42 kg*m/s^2}{6kg}

Divide. When we divide, the kg in the numerator and denominator will cancel each other out.

a=\frac{42}{6}m/s^2

a= 7 m/s^2

The acceleration of the object is 7 meters per square seconds.

Which expression of distance uses SI units? A. 30 miles B. 16 kilograms C. 24 feet D. 500 meters
Stella [2.4K]
Hi!

SI units are physical measurements which will be in the form of kilograms, second, kelvin, metres, etc.

Since kilograms measure the weight of an object, it is out. Miles and feet are not SI units, so they are also out. This only leaves one answer left!

Hopefully, this helps! =)
