013 (part 1 of 2) 10.0 poin
A model airplane of mass 1.1 kg is attached
to a horizontal string and flies in a horizontal
circle of radius 5.3 m, making 1.2 revolutions
every 8 s. (The weight of the plane is balanced
by the upward "lift" force of the air on the
wings of the plane.)
The accelaration due to the gravity is 9.81
m/s
Find the speed of the plane.
Answer in units of m/s.
Find the tension in the string.
Answer in units of N
