After narrowly escaping the crocodile, you follow the river on foot. Later, you see a deer heading into the water (m = 50kg, vi = 3 m/s West) and the same giant crocodile (m = 180 kg) leaps from the water to attack! If the crocodile leaps from the water with vi = 8 m/s East and the two collide inelastically, what is their final velocity? Include direction in your answer! PSA: this is for physics on the subject of momentum
