Question

A 45 kg woman runs at a speed of 5.6 m/s. What is her momentum?

A) 252 kg∙m/s
B) 224 kg∙m/s
C) 196 kg∙m/s
D) 280 kg∙m/s

Answer 1

The momentum of a 45 kg woman running at a speed of 5.6 m/s is calculated by multiplying mass by velocity, which gives us 252 kg·m/s. Option A) is the correct answer.

Step-by-step explanation:

The momentum of an object is defined as the product of its mass and its speed. In this case, the momentum (p) of a 45 kg woman running at a speed of 5.6 m/s can be calculated using the formula p = mv, where m is mass and v is velocity.

To find her momentum, simply multiply her mass by her velocity:

p = 45 kg × 5.6 m/s

p = 252 kg·m/s

Therefore, the correct answer is A) 252 kg·m/s.
