Determine the final angular speed after an elapsed time of 2s. Initial angular velocity Wo -13.0 rad/s Angular acceleration a +5.0 rad/s^2

Answer 1

To determine the final angular speed after an elapsed time of 2s, we can use the formula:

ωf = ω0 + αt

Where:
ωf is the final angular speed
ω0 is the initial angular velocity
α is the angular acceleration
t is the elapsed time

Given:
ω0 = -13.0 rad/s
α = +5.0 rad/s^2
t = 2s

Plugging in the values, we have:

ωf = -13.0 rad/s + (5.0 rad/s^2)(2s)
ωf = -13.0 rad/s + 10.0 rad/s
ωf = -3.0 rad/s

Therefore, the final angular speed after an elapsed time of 2s is -3.0 rad/s.
