A spacecraft forms a circular orbit at an altitude of $150 \mathrm{~km}$ above the surface of a spherical Earth. Assuming the gravitational parameter, $\mu=3.986 \times 10^{14} \mathrm{~m}^{3} / \mathrm{s}^{2}$ and radius of earth, $\mathrm{R}_{\mathrm{E}}=6,400 \mathrm{~km},$ the velocity required for the injection of the spacecraft, parallel to the local horizon, is______________ $\quad$ (accurate to two decimal places).
