Question

A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass?

Answer 1

Answer:

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

• Force F = 500 N

• Acceleration a = 75 m/s²

To determine

Mass m = ?

Important Tip:

• The mass of a rock can be found using the formula F = ma

Using the formula

$F = ma$

where

• F is the force (N)

• m is the mass (kg)

• a is the acceleration (m/s²)

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

$F = ma$

$500 = m(75)$

switch sides

$m\left(75\right)=500$

Divide both sides by 75

$\frac{m\cdot \:75}{75}=\frac{500}{75}$

simplify

$m=\frac{20}{3}$

$m=6.7$ 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.
