The Lockheed SR-71 Blackbird is a high-altitude spy plane and the current official record speed holder. Fully loaded, the Blackbird has a mass of 7.7 x 10 4 kg, and at
top speed it has a kinetic energy of 3.7 x 10 10 J. What is the top speed of the SR-71?

answer

the arrows to the right of earth should point up.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
