Answer to Problem 4P

  226.7rad/s2

Explanation of Solution

Given:

RPM of the Blades, RPM=6500 .

Time taken to come to rest, t=3s .

Formula used:

  rad/s=RPM×π30 .

  α=ωt

Where

  α is angular acceleration.

  ω is angular velocity.

  t is time taken.

Calculation:

Substituting the given values

  ω =Velocity in rad/s = 6500×π30 = 680.3rad/s .

Therefore, acceleration will be:

  α=680.33=226.7rad/s2 (negative because it is slowing down).

Conclusion:

Thus, the angular acceleration of the blades is 226.7rad/s2 .
