A cylinder with a diameter of 35.9 cm is initially at rest. It is then given an angular acceleration of [tex]$10.1 \, \text{rad/s}^2$[/tex]. Find the tangential speed of the outer edge of the cylinder at [tex]$5.82 \, \text{s}$[/tex]. Give your answer in m/s.

Answer :

The tangential speed of the outer edge of the cylinder at 5.82 s is approximately 10.571 m/s.

To find the tangential speed of the outer edge of the cylinder, we can use the equation:

v = r * ω

Where:

v is the tangential speed,

r is the radius of the cylinder, and

ω is the angular velocity.

Given:

Diameter of the cylinder = 35.9 cm = 0.359 m (since 1 m = 100 cm)

Radius of the cylinder, r = 0.359 m / 2 = 0.1795 m

Angular acceleration, α = 10.1 rad/s²

Time, t = 5.82 s

First, let's find the angular velocity at time t using the equation:

ω = ω₀ + α * t

Where:

ω₀ is the initial angular velocity (which is 0 since the cylinder is initially at rest).

ω = 0 + 10.1 rad/s² * 5.82 s

ω ≈ 58.842 rad/s

Now, we can substitute the values into the tangential speed equation:

v = r * ω

v = 0.1795 m * 58.842 rad/s

v ≈ 10.571 m/s

Therefore, the tangential speed of the outer edge of the cylinder at 5.82 s is approximately 10.571 m/s.
