Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that experienced by the truck. To substantiate this view, they point out that the car is crushed, whereas the truck in only dented. This idea of unequal forces, of course, is...

Suppose a car experienced a head-on collision in Cartoon world. (in the calculation, round to nearest integer) 1. Before the collision, the mass of the car is 1500kg, and the speed is 36km/hr, and the car is going to the north. What is its momentum? Is its momentum a vector? If it is a vector, indicate it's direction and magnitude. (We can define the north as the positive direction in the following calculation) 2. There is a truck heading south,...
