A firecracker of mass 5.00 kg is shot up in the air and is traveling upwards with speed vi when it explodes into two pieces: a m1 = 2.00 kg piece which is expelled horizontally with a speed of v1 = 24.0 m/s, and a m2 = 3.00 kg piece which is expelled with a speed v2 at an angle θ = 45° from the horizontal. What was the speed vi of the firecracker at the moment before it exploded?a. 9.6 m/sb. 6.8 m/sc. 19.2 m/sd. 13.6 m/s V1Vi
