Question

A satellite in a circular orbit receives a tangential impulse so that its speed becomes √2 times the circular speed. Its subsequent path is:

G1 Physics · Accepted Answer

At radius r, v_c=√(GM/r) and escape speed v_e=√(2GM/r)=√2v_c. Thus the new speed is exactly escape speed and the orbit is parabolic.
