In 9 sec, it increases the angular velocity by (0.45 x 9) rad/s which will give us 4.05 rad/s
Now get the angular velocity and divide it 2pi = 4.05 by 2(pi) to give how many revolutions 4.05 rad is equivalent to = 0.6446 rps
Them, multiply this by 60 to get it from rps to rpm increase (0.6446 x 60)=38.676 rpm
Add this and the starting revolution frequency of 49 rpm to give: (49 rpm + 38.676 rpm) = 87.6760 rpm
Answer:
True
Explanation:
