Question

5. A runner of mass 60 kg accelerates at 2.0 m/s2 at the start of a
race. Calculate the force provided from her legs.​

Answer 1

Answer:

F = 120 N

Explanation:

Given that,

The mass of a runner, m = 60 kg

Acceleration of the runner, a = 2 m/s²

We need to find the force provided from her legs. The formula for force is given by :

F = ma

Substitute all the values,

F = 60 kg × 2 m/s²

= 120 N

So, the required force is equal to 120 N.

Answer 2

The provided force will be "120 N".

Given:

Mass,

• m = 60 kg

Acceleration,

• a = 2.0 m/s²

As we know that,

→ $Force = Mass\times Acceleration$

or,

→ $F = ma$

then,

      $= 60\times 2.0$

      $= 120\ N$

Thus the above answer is right.
