Solve the problem
-An object is spinning around a circle with a radius of 24 centimeters. If in 14 seconds a central angle of $\frac { 1 } { 4 }$ radian has been covered, what is the linear speed of the object?
A) $\frac { 6 } { 7 } \mathrm {~cm}$ per sec
B) $84 \mathrm {~cm}$ per sec
C) $24 \mathrm {~cm}$ per sec
D) $\frac { 3 } { 7 } \mathrm {~cm}$ per sec

Quizplus · Accepted Answer

The linear speed $ v $ is given by $ v = r \theta / t $, where $ r = 24 $ cm, $ \theta = \frac{1}{4} $ radian, and $ t = 14 $ seconds. Thus, $ v = \frac{24 \times \frac{1}{4}}{14} = \frac{3}{7} $ cm per sec.
