Question

What force gives a 1.0 kg mass an acceleration of 7.0 m/s^2?​

Answer 1

7N

Step-by-step explanation:

From Newton's law of motion, F=ma where m is mass, a is acceleration. Since we're given mass as 1 kg and acceleration as 7 m/s2 then we substitute them directly into the above formula to get force, F.

By substitution of the above figures, F=1*7=7N

Therefore, the magnitude of force is 7N

Answer 2

For this case we have that according to Newton's second law it is true that:

`F = m * a`

Where:

F: It is the force

m: It is the mass

a: It is the acceleration

According to the data we have:

`m = 1.0 \ kg\\a = 7.0 \frac {m} {s ^ 2}`

So, we have:

`F = 1.0 \ kg * 7.0 \frac {m} {s ^ 2}\\F = 7 \ N`

Thus, the applied force will be 7 Newtons.

Answer:

`F = 7 \ N`
