QUESTION:

Problem 26PE

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.

ANSWER:

Solution 26 PE

Step 1 of  1

The velocity of the car after hitting the deer can be found by using the principle of conservation of momentum which states that For a collision occurring between object1 and object2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

=

Here, mc = mass of the car = 900 kg,

         md = mass of the deer = 150 kg
