Question

Your friends sit in a sled in the snow. If you apply a force pf 75 N to them, they have an acceleration of 0.9 m/s ^ 2. What is their mass?

Answer 1

Mass of the sled in the snow 83.33 kg.

Step-by-step explanation:

Given that,

Force applied to move the sled in the snow (F) = 75N

`\text { Acceleration }(a)=0.9 \mathrm{m} / \mathrm{s}^(2)`

We know that

Newton's second law of motion is

`\text { Force }=\text { mass } * \text { acceleration }`

F = ma (Or "force" is equal to "mass" times "acceleration".)

So if we move this around we can isolate mass and get mass

`\text { Mass }=\frac{\text { force }}{\text { accelearation }}`

`\mathrm{M}=(75)/(0.9)`

M = 83.33 kg

Mass of the sled in the snow 83.33 kg.
