Answer:
Explanation:
The definition of acceleration is the change in velocity over a period of time. If the girl's velocity is constant, that means it's not changing. Therefore, acceleration is 0 m/s/s
Answer:
The force experienced is 375 N.
Explanation:
Here,
Mass of the object( M)= 75 kg
Acceleration of the body(a) =5 m/s²
Force required to accelerate the body( F) =?
Then, we know ,
From newton's second law of motion,

=
=375 kgm/s²
= 375 Newton
So, The force experienced by the 75 kg body that undergoes an acceleration of 5 m/s² is 375 N.
