Final answer:
The force of friction acting on the 1.5 kg object that is being pushed with a force of 1.2 N and has an acceleration of 0.50 m/s² is 0.45 N.
Step-by-step explanation:
To determine the force of friction acting on an object with a mass of 1.5 kg that is being pushed with a force of 1.2 N and accelerates at 0.50 m/s², we can use Newton's second law of motion, which states F = ma, where F is the net force acting on the object, m is the mass of the object, and a is its acceleration.
Given that the net force (Fnet) is the difference between the applied force and the force of friction (Fr):
Fnet = applied force - Fr
m * a = applied force - Fr
Fr = applied force - (m * a)
Plugging in the given values:
Fr = 1.2 N - (1.5 kg * 0.50 m/s²)
Fr = 1.2 N - 0.75 N
Fr = 0.45 N
Therefore, the force of friction acting on the object is 0.45 N.
