A spacecraft forms a circular orbit at an altitude of 150 km above the surface of a spherical Earth. Assuming the gravitational parameter, μ=3.986×1014 m3/s2 and radius of earth, RE=6,400 km. the velocity required for the injection of the spacecraft, parallel to the local horizon, is ________ (accurate to two decimal places).
Correct : 7.80 to 7.80 (or) 7800 to 7802
