Answer:
-100 kg · m/s
Explanation:
We can find the momentum of an object using the formula:
- p = mv
- where p = momentum (kg * m/s), m = mass (kg), v = velocity (m/s), and p and v are vectors
Let's start by converting the mass of the object to kilograms.
Since the left direction is the negative direction, we know that the velocity of the object is -25 m/s.
Using these variables, we can solve for p in the formula.
- p = mv
- p = (4 kg)(-25 m/s)
- p = -100 kg · m/s
The momentum of the object is -100 kg · m/s.
