Question

A remote control model airplane connected to a string is flown in a circle with a radius of

0.348 m about a fixed axis with an angular velocity of +1.47 rad/s. The plane’s throttle is

increased, so that it acquires an angular acceleration of 2.18 rad/s^s.

elapsed since the plane sped up, what is the

airplane? (See figure below.)

A. 2.37 m/s

E. 2.93 m/s

A remote control model airplane connected to a string is flown in a circle with a radius of 0.348 m about a fixed axis with an angular velocity of +1.47 rad/s. The plane's throttle is increased, so that it acquires an angular acceleration of 2.18 rad/s^s. After 0.490 s have elapsed since the plane sped up, what is the total acceleration ( ) (in m/s2) of the C. 2.24 m/s D. 0.76 m/s airplane? (See figure below.) A. 2.37 m/s B. 6.71 m/s E. 2.93 m/s
