Question

your friends sit in a sled in the snow. If you apply a force of 120 N to them, they have an acceleration of 1.3 m/s^2.what is their mass?

Answer 1

The formula to use is:

`f = m * a`
Using the given numbers this makes:

`120 = m * 1.3 \\ m = 120 / 1.3 = 92.3 kg`

Answer 2

Mass of the sled, m = 92.30 kg

Step-by-step explanation:

It is given that, your friends sit in a sled in the snow.

Force applied on the sled, F = 120 N

Acceleration,
`a=1.3\ m/s^2`

We need to find the mass of the sled. The force acting on the sled is equal to the mass of the sled and the acceleration produced i.e.

`F=ma`

`m=(F)/(a)`

`m=(120\ N)/(1.3\ m/s^2)`

m = 92.30 kg

So, the mass of the sled is 92.30 kg. Hence, this is the required solution.
