Problem 3E

CP CALC The angular velocity of a flywheel obeys the equation ωz(t) = A + Bt2, where t is in seconds and A and B are constants having numerical values 2.75 (for A ) and 1.50 (for B ). (a) What are the units of A and B if ωz is in rad/s? (b) What is the angular acceleration of the wheel at (i) t = 0 and (ii) t = 5.00 s? (c) Through what angle does the flywheel turn during the first 2.00 s? ( Hint: See Section 2.6.)

Step-by-Step Solution:

Solution 3E

Step 1:

(a).we know from dimensional analysis that the dimensions of each side of the equation must match up therefore the dimensions of A are and the dimensions of B are since t will have the dimension Step 2 of 3

Step 3 of 3
