14/15 please help

14. A 20 kg bomb is at rest when it explodes into three pieces. A 2.50 kg * 1 point piece moves south at 350 m/s and a 14.0 kg piece west at 95.0 m/s. Calculate the speed of the 3rd piece. Your answer Use the following information to answer question 15. In a movie stunt, a car and a train locomotive intentionally crash. The collision is illustrated in the diagram below. Train track Train locomotive m = 4.5 x 10 kg v = 10.0 m/s N Truck m =3.0x 10' kg v = 33.3 m/s 15. Calculate the magnitude of the total momentum of the system * 1 point immediately AFTER the collision. (include units) Your
