Answer:
a = 40 [m/s^2]
Explanation:
This problem can be solved using Newton's second law which tells us that the sum of forces acting on a body must be equal to the product of mass by acceleration.
F = m*a
where:
m = mass = 0.4 [kg]
F = force = 16 [N]
a = acceleration [m/s^2]
Now replacing we have:
16 = 0.4*a
a = 40 [m/s^2]
To solve this there is this website that I found that helps
I am in middle school so I have no idea how to solve this
but
this website may help considering u are in high school and u
(hopefully mind u)
know how to solve this
so to get there u google
"whats impact speed"
and click on the first thing there the website is ehow
I also agree to A. The force will always pull back a lot deals with gravitational pull
