Question

An object with a mass of 90 grams, moving at a constant velocity of 6 meters per second, has __________.
A. a momentum of 540 gram meters per second
B. an acceleration of 10 meters per second squared
C. a momentum of 90 gram meters per second
D. an acceleration of 6 meters per second squared

Answer 1

An object with a mass of 90 grams, moving at a constant velocity of 6 meters per second has a momentum of 540 gram metres per second.

• Mass of object = 90 g
• Velocity of object = 6 m/s.

Now, momentum of an object is a vector quantity represented as the product of mass and velocity of the object.

$P = m \times v$

$\implies P = 90 \times 6$

$\implies P = 540 \: g \: m/s$

So, the object has a momentum of 540 g m/s.
