Respuesta :
The relation between force, mass of an object and its acceleration is given by following equation
F = mass of object X acceleration
The unit of Force is Newton (N)
unit of acceleration is ms⁻²
unit of mass if Kg
[all these are SI units]
Mass of object =[tex]\frac{Force}{acceleration}[/tex]
mass of sprinter =[tex]\frac{650}{10}=65kg[/tex]
Answer:
The mass of sprinter is 65 kg.
Explanation:
Force is defined as the push or pull on an object with some mass that causes change in its velocity.
It is also defined as the mass multiplied by the acceleration of the object.
Mathematically,
[tex]F=ma[/tex]
where,
F = force exerted on starting blocks = 100 N
m = mass of the sprinter = ?
a = acceleration of the sprinter = [tex]10 m/s^2[/tex]
Putting values in above equation, we get:
[tex]650 kg.m/s^2=m\times 10m/s^2\\\\m=\frac{650 N}{10 m/s^2}=65kg[/tex]
Hence, the mass of sprinter is 65 kg.
