Question

An object with a mass of 120 kilograms is moving at a velocity of 60 m/s. What's its momentum?
Question 14 options:

A)

7,200 kg-m/s

B)

3,600 kg-m/s

C)

2 kg-m/s

D)

0.5 kg-m/s

Answer 1

Momentum is calculated using the formula:

\[
\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)
\]

For the given object:

- Mass \( m = 120 \) kg
- Velocity \( v = 60 \) m/s

Now, substituting the values into the formula:

\[
p = 120 \, \text{kg} \times 60 \, \text{m/s} = 7200 \, \text{kg-m/s}
\]

So the momentum of the object is \( 7,200 \, \text{kg-m/s} \).

The correct answer is A) 7,200 kg-m/s.
