Answer :
Answer:
A: The mass would be 250kg
Explanation:
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
p= mv
m= p/ v
The explanation to that is:
momentum = mass× velocity
mass= momentum / velocity
THE ANSWER IS A
Hope this helps!

Final answer:
To find the mass of an object with a known momentum and velocity, one uses the formula m = p / v. Substituting the given values (momentum of 200 kg-m/s and velocity of 0.8 m/s), the mass is calculated to be 250 kg.
Explanation:
The question concerns the concept of momentum in physics, which is the product of an object's mass and its velocity. Momentum (p) is given by the equation:
p = m \(\cdot\) v
where:
- p is the momentum
- m is the mass of the object
- v is the velocity of the object
To find the mass of an object when given its speed and momentum, you rearrange the equation to solve for m:
m = p / v
Substituting the given values:
m = 200 kg-m/s \/ 0.8 m/s = 250 kg
Therefore, the mass of the object is 250kg, which corresponds to answer choice A.
