The equation to find force is f=ma. So, if you plug in the information that you have you'll get F=5x3 and that'll equal F=15N
I need a picture plz I don’t know what to answer.
A) 
The total energy of the system is equal to the maximum elastic potential energy, that is achieved when the displacement is equal to the amplitude (x=A):
(1)
where k is the spring constant.
The total energy, which is conserved, at any other point of the motion is the sum of elastic potential energy and kinetic energy:
(2)
where x is the displacement, m the mass, and v the speed.
We want to know the displacement x at which the elastic potential energy is 1/3 of the kinetic energy:
Using (2) we can rewrite this as
And using (1), we find
Substituting 
into the last equation, we find the value of x:
B) 
In this case, the kinetic energy is 1/10 of the total energy:
Since we have
we can write
And so we find:
Answer:
the bowling ball, because it has more mass and therefore more inertia
Explanation:
As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.
Inertia is the property of mass of an object which always resist to change the state of motion of the object.
If an object has more inertia then it is more difficult to change the state of motion.
Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.
So correct answer will be
the bowling ball, because it has more mass and therefore more inertia
