What is the velocity of a 900-kg car initially moving at 30.0 m/s, just after it hits a 150-kg deer initially running at 12.0 m/s in the same direction? Assume the deer remains on the car.

Step-by-step solution In this problem we have to calculate the velocity of car after it hits a deer moving in the same direction by using the given data respectively: Step 1 of 3 The relation of masses of each of them and velocity after sticking together (law of conservation of momentum: …… (1) Here is the mass of car, is the mass of deer, is the velocity of car, is the velocity of deer, and v is the final velocity.
