When an airplane flies faster than the speed of sound, the sound waves that are formed take on a cone shape, and where the cone hits the ground, a sonic boom is heard. If
Is the angle of the vertex of the cone, then
Where V is the speed of the plane and M is the machnumber, then what is the speed of the plane if the cone angle is 60o
Round to the nearest whole number.Speed of the plane is __________ m/sec.
A) Speed of the plane is 660 m/sec.
B) Speed of the plane is 381 m/sec.
C) Speed of the plane is 165 m/sec.
D) Speed of the plane is 101 m/sec.
