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

Answer:

The correct answer is "140.8 N".

Explanation:

Given:

Mass,

m = 88 kg

Acceleration,

a = 1.60 m/s²

Now,

The net external force for him will be:

⇒ $F_{ext}=Mass\times Acceleration$

By putting the values, we get

           $=88\times 1.60$

           $=140.8 \ N$
