Question

An 88.0 kg sprinter starts a race with an acceleration of 1.60 m/s2. What is the net external force (in N) on him

Answer 1

The correct answer is "140.8 N".

Step-by-step explanation:

Given:

Mass,

m = 88 kg

Acceleration,

a = 1.60 m/s²

Now,

The net external force for him will be:

⇒
`F_(ext)=Mass* Acceleration`

By putting the values, we get

`=88* 1.60`

`=140.8 \ N`
