Question

What applied force is needed by a 5kg to accelerate 10 m/s2?

Answer 1

`F_"net" = 50 N`

Explanation:

Newton's 2nd Law says that

`F_"net" = m*a`

So, plugging in your data, `F_"net" = 5 kg*10 m/s^2 = 50 (kg*m)/s^2`

So the answer is `F_"net" = 50 N`.

I hope this helps,

Answer 2

`50` newtons

Explanation:

We use Newton's second law of motion, which states that,

`F=ma`

where:

• `F` is the net force applied in newtons

• `m` is the mass of the object in kilograms

• `a` is the acceleration of the object in meters per second squared

So, we get:

`F=5 \ "kg"*10 \ "m/s"^2`

`=50 \ "N" \ (because 1 \ "N"-=1 \ "kg m/s"^2)`
