Problema Solution
According to Newton's Second Law of Motion, the force acting on an object varies directly with the object's acceleration. Suppose that a force of
32 N
results in an acceleration of
8 /ms2
. If the object's acceleration becomes
7 /ms2
, what is the force?
Answer provided by our tutors
If 'F' denotes the force and 'a' the acceleration we have:
F = C*a, where C is constant (the force acting on an object varies directly with the object's acceleration)
F/a = C
Suppose that a force of 32 N results in an acceleration of 8 m/s^2 and the force of 'x' N results in an acceleration of 7 m/s^2.
Now we can write:
32 / 8 = x / 7

x = 28 N
The force of 28 N results in an acceleration of 7 m/s^2.
