Question

25. An astronaut applies a force of 500 N to an asteroid, and it accelerates at 7.00 m/s². What is the asteroid's mass?

a. 71 kg
b. 135 kg
c. 441 kg
d. 3 500 kg​

Answer 1

Step-by-step explanation:

We can use Newton's second law of motion, which states that force equals mass times acceleration (F=ma), to solve this problem. Rearranging the formula, we get:

m = F/a

Substituting the given values, we get:

m = 500 N / 7.00 m/s²

m = 71.43 kg

Therefore, the mass of the asteroid is approximately 71 kg, which is closest to option (a).
