A firecracker was thrown vertically upwards with a speed of $20 \mathrm{~m/s}$. Three seconds after the start of the flight, it exploded into two fragments of equal mass. The first fragment flew horizontally immediately after the explosion with a speed of $48 \mathrm{~m/s}$. Find the speed of the second fragment (in m/s) right after the explosion. Assume the acceleration due to gravity is $10 \mathrm{~m/s}^2$.
