Question

1) An object rotating at 500 rpm (rev/min) is spinning faster than an object rotating at 500 rad/s. True False

2) If you're goin to calculate an object's tangenital velocity from its angular velocity, the angular velocity can be expressed in either rad/s or rev/min True false

3) Tangential acceleration is measured in m/s^2 true false

Answer 1

false

false

true

Answer 2

1) An object rotating at 500 rpm (rev/min) is spinning faster than an object rotating at 500 rad/s. True False

2) If you're goin to calculate an object's tangenital velocity from its angular velocity, the angular velocity can be expressed in either rad/s or rev/min True false

3) Tangential acceleration is measured in m/s^2 true false

Answer 3

Part 1)

False

500 rpm converts by multiplying by 2pi rads per rev and dividing 60 sec per min

500 rpm = 52.4 rad/s

Thus 500 rad/s is faster than 52.4 rad/s (which was 500 rpm

2)

3) Tangential acceleration is measured in m/s^2 true false

Please rate me. Thanks a lot.
