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?

Question

A firecracker of mass 5.00 kg is shot up in the air and is traveling upwards with speed v_i 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 v_i of the firecracker at the moment before it exploded?
