Explanation:
Momentum is the product of mass and velocity.
The mass of the truck is 2,000 kilograms and the velocity is 35 meters per second.
Substitute the values into the formula and multiply.
The truck's momentum is <u>70,000 kilograms meters per second.</u>
Car X traveled 3d distance in t time. Car Y traveled 2d distance in t time. Therefore, the speed of car X, is 3d/t, the speed of car Y, is 2d/t. Since speed is the distance taken in a given time.
In figure-2, they are at the same place, we are asked to find car Y's position when car X is at line-A. We can calculate the time car X needs to travel to there. Let's say that car X reaches line-A in t' time.
Okay, it takes t time for car X to reach line-A. Let's see how far does car Y goes.
We found that car Y travels 2d distance. So, when car X reaches line-A, car Y is just a d distance behind car X.
