Answer:
Momentum, p = 23250 kg m/s
Explanation:
Given that
Mass of a car, m = 1550 kg
Speed pf car, v = 15 m/s
We need to find the momentum of the car. The formula for the momentum of an object is given by :
p = mv
Substituting all the values in the above formula
p = 1550 kg × 15 m/s
p = 23250 kg m/s
So, the momentum of the car is 23250 kg m/s.

<h2>Explanation:</h2>
We can use voltage divider to solve this problem that is defined as the passive linear circuit producing an output voltage 
that is a fraction of its input voltage 
. So we can use the formula:
