Question

If the sled has a mass of 6.0 KG what is the mass of your little sister

Answer 1

Given:

• Mass, m = 6.0 kg

,

• Force = 110 N

,

• acceleration, a = 2.2 m/s²

Let's find the mass of your little sister.

Let's first find the total mass:

`F=m* a`

Where:

F is the force

m is the total mass

a is the acceleration.

Rewrite the formula for m, and solve:

`\begin{gathered} m=(F)/(a) \\ \\ m=(110)/(2.2) \\ \\ m=50kg \end{gathered}`

The total mass is 50 kg.

Now, to find the mass of your sister, we have:

Total mass = mass of sister + mass of sled

Mass of sister = Total mass - mass of sled

Mass of sister = 50kg - 6.0 kg = 44 kg.

Therefore, the mass of your little sister is 44.0 kg
