Question

Find the mass. 10 points. Will give brainliest.

Answer 1

Answer:

3.94 kg

Explanation:

Given,

Force ( f ) = 30 N

Acceleration(a) = 7.6 m/s

Now, Let's find the mass of the ball

Using the Newton's second law of motion:

We get:

$force \: = mass \: \times acceleration$

plug the value

$30 \: = m \: \times 7.6$

Use the commutative property to reorder the terms

$30 = 7.6 \: m$

Swap the sides of the equation

$7.6m = 30$

Divide both sides of the equation by 7.6

$\frac{7.6 \: m}{7.6} = \frac{30}{7.6}$

Calculate

$m = 3.94 \: kg$

Hope this helps..

Best regards!!

Answer 2

Answer:

$\displaystyle \boxed{\mathrm{3.95 \: kg }}$

Explanation:

$\mathrm{force \: (N) = mass \: (kg) \times acceleration \: (m/s^2)}$

$\mathrm{force = 30N}$

$\mathrm{acceleration = 7.6 \: m/s^2 }$

$\mathrm{Find \: the \: mass.}$

$\mathrm{30 = m \times 7.6}$

$\displaystyle \mathrm{m =\frac{30}{7.6} }$

$\displaystyle \mathrm{m = 3.947... }$
