The speed or the linear velocity of the stone is 9.93 m/s; option C
<h3>What is the speed or linear velocity of the stone?</h3>
The linear velocity of the stone is given by the formula below:
where w is angular velocity and r is radius.
w = θ/t
1 complete revolution = 2π radians
5 revolutions = 10π radians
w = 10π/4.4 rad/s
v = 10π/4.4 rad/s * 1.4
v = 9.93 m/s
In conclusion, the linear velocity is obtained from the angular velocity and radius of the string.
