a 2 kg mass accelerates at 20 m/s/s while being pushed by a 44 N force. Find the force of friction.
Net force = Force pushing - Force friction.
The net force here is 2 kg x 20 m/s/s.
To find the net force, multiply the mass (2 kg) by the acceleration (20 m/s^2):
Net force = 2 kg x 20 m/s^2 = 40 N.
Now, we can use the net force to find the force of friction. From the given information, we know that the force pushing the object is 44 N. So, the equation becomes:
40 N = 44 N - Force friction.
To find the force of friction, we rearrange the equation:
Force friction = 44 N - 40 N = 4 N.
Therefore, the force of friction in this scenario is 4 N.
