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)

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.

We have to convert to SI units.

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.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

80cm/s.

24cm/s.

53.3cm/s.
