Starting from rest, an engine turbine rotates until it reaches an angular velocity of 1,200 rad/s. If the angular acceleration of the engine is 25 rad/s2, how long does it take the engine turbine to reach this angular velocity?
48 s
0.021 s
30,000 s
57,600 s
A wheel completes 100 revolutions around a central axis point. If the wheel started at rest and it takes 12 s to complete this distance, what is the angular acceleration of the wheel?
8.73 rad/s2
104.72 rad/s2
1.39 rad/s2
16.67 rad/s2
A top completes 200 revolutions around. How would you convert that radians?
Divide by 2π
Multiply by 2π
Divide by π
Multiply by π
α = 3/2 rad/s2
α = 2/3 rad/s2
α = 2/3 rad/s2
α = 6 rad/s2
A gear spins at a rate of 400 revolutions/minute. Which choice is closest to its angular speed in radians/second?
6.67 rad/s
2500 rad/s
41.9 rad/s
20.9 rad/s
How many radians make up one revolution of 360 degrees?
π/2
π
2π
3π/2
