Question

A 8.78 g bullet is moving horizontally. What is the bullet's momentum if its velocity is 300 m/s?

a) 2.634 kg m/s
b) 26.34 kg m/s
c) 263.4 kg m/s
d) 2634 kg m/s

Answer 1

The bullet's momentum can be calculated using the equation momentum = mass × velocity. Plugging in the given values, the momentum is 2.634 kg m/s.

Step-by-step explanation:

The bullet's momentum can be calculated using the equation momentum = mass × velocity. Plugging in the given values, the momentum is 2.634 kg m/s.

To calculate the momentum of a bullet, we can use the equation:

momentum = mass × velocity

Given that the mass of the bullet is 8.78 g (or 0.00878 kg) and its velocity is 300 m/s, we can plug these values into the equation:

momentum = 0.00878 kg × 300 m/s = 2.634 kg m/s

Therefore, the bullet's momentum is 2.634 kg m/s (option a).
