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 mo

mentum? 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)

Answer:

Momentum = 15000 kg·m/s

It is a vector.

Its direction is north and its magnitude is 15000 kg·m/s

Explanation:

Momentum is the product of mass and velocity.

$P = mv$

We have to convert to SI units.

$P = (1500\ \text{kg})\left(\dfrac{36000\ \text{m}}{3600\ \text{s}}\right) = 15000\ \text{kg}\cdot\text{m/s}$

Momentum is a vector because it is the product of a scalar (mass) and a vector (velocity). It points in the direction of the velocity, in this case, north. Its magnitude is as found above.
