A force is applied to a 30-kg object, resulting in an acceleration of 15 m/s. What is the force being applied to the object?
From Second Newton's Law:
F=am
a=\(15 \frac{m}{ s^{2} }\)
m=30kg
F=\(15 \frac{m}{ s^{2} }\)30kg=450N
The sum of all forces applied to the object = (mass) x (acceleration)
The sum of all forces applied to the object = (30) x (15)
= 450 newtons, in the direction of the acceleration.
