A 3000 n force acts on a 200 kg object what is the acceleration of the object
2 answers:
Explanation:
As we know that relation between force, mass and acceleration is as follows.
F = ma
where, F = force
m = mass
a = acceleration
So, it is given that force is 3000 N and mass is 200 kg. Hence, calculate the acceleration as follows.
F = ma
3000 N =
a =
=
Thus, we can conclude that acceleration of the given object is .

Answer:
Explanation:
As we know that the that the Astronaut dropped a stone on the surface of the planet takes 0.420 s to fall a distance of d = 1.90 m
so we will have
now we know that the acceleration due to gravity is given as
so we will have
The question is missing, however, I guess the problem is asking for the value of the force acting between the two balls.
The Coulomb force between the two balls is:
where
is the Coulomb's constant, 
is the intensity of the two charges, and 
is the distance between them.
Substituting these numbers into the equation, we get
The force is repulsive, because the charges have same sign and so they repel each other.
