Se dinamita una roca la cual se fragmenta en tres partes: m1= 12kg, m2= 25 kg y m3= 8 kg. Las dos primeras salen disparadas formando entre sí un ángulo de 50grados, con rapideces v1= 20 m/s y v2= 14 m/s. Determina: magnitud y dirección de la velocidad y la cantidad de movimiento del tercer fragmento: Utiliza un sistema de coordenadas rectangulares.
