Question

What is the momentum of a child and wagon if the total mass of the child and wagon is 23 kg and the velocity is 1.75 m/s?

a. 40.25 kg m/s
b. 28.75 kg m/s
c. 18.05 kg m/s
d. 33.25 kg m/s

Answer 1

The momentum of a child and wagon with a total mass of 23 kg and a velocity of 1.75 m/s is 40.25 kg m/s, which is option (a).

Step-by-step explanation:

The momentum of an object can be calculated by the formula momentum = mass × velocity. So for the child and wagon with a total mass of 23 kg and a velocity of 1.75 m/s, the momentum can be calculated as follows:

Momentum = 23 kg × 1.75 m/s

Momentum = 40.25 kg·m/s

So the correct answer to the student's question is 40.25 kg m/s, which corresponds to option (a).
