A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass? A. 575 kg
B. 3.8 x 104 kg
C. 0.15 kg
D. 6.7 kg

We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

Explanation:

Given

To determine

Mass m = ?

Important Tip:

Using the formula

where

now substituting F = 500, and a = 75 m/s² in the formula

switch sides

Divide both sides by 75

simplify

kg

Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.
