Answer:
The horizontal force is 780 N.
Explanation:
Given that,
Mass of sprinter = 52 kg
Suppose A world-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15 m/s².
We need to calculate the horizontal force
Using formula of force
[tex]F = ma[/tex]
Where, m = mass of sprinter
a = acceleration
Put the value into the formula
[tex]F=52\times15[/tex]
[tex]F=780\ N[/tex]
Hence, The horizontal force is 780 N.
