How do I find tangential speed with just radius, time and angular acceleration?

tangential speed= radius*angularspeed

tangential speed=radius*(angularacceleration*time)

Can I just do that when my radius is in radians?

radius is in linear units, not radians.

My bad...

I meant the angular acceleration - I was given rad/sec^2 as the units.

To find the tangential speed using the radius, time, and angular acceleration, you can follow these steps:

1. Find the angular velocity (ω) using the formula: ω = θ/t, where θ is the angular displacement and t is the time.

2. Calculate the tangential acceleration (at) using the formula: at = r*α, where r is the radius and α is the angular acceleration.

3. Use the equation of motion: vf = vi + at, where vf is the final tangential velocity, vi is the initial tangential velocity (usually considered zero), and at is the tangential acceleration calculated in the previous step.

4. If the initial tangential velocity is zero (vi = 0), the final tangential velocity (vf) will be equal to the tangential speed.

Therefore, the tangential speed can be determined by substituting the values into the formula vf = at.
