Answer:
2m/s²
Step-by-step explanation:
If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:
F∝a
F = ka.
F is the force
a is the object's acceleration
From the expression;
k is the constant of proportionality
When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then
k = 25/5
k = 5Ns²/m
If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above
F = ka
Given F = 10N and k = 5Ns²/m
a = F/k = 10/5
a = 2m/s²
The acceleration of the object will be 2m/s²
