An object of mass 1,5 kg,is pulled along a rough horizontal surface by a horizontal force F.calculate the value of F if the force of friction is 1,3 N and the object accelerates at 2m.s-2
To calculate the value of the applied force (F), we will use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Given:
Mass of the object (m) = 1.5 kg
Acceleration (a) = 2 m/s^2
Force of friction (f) = 1.3 N
We can express Newton's second law as the following equation:
F = m * a
Substituting the given values, we get:
F = 1.5 kg * 2 m/s^2
F = 3 N
So, the value of the applied force (F) is 3 Newtons.
