A table with a mass of 100 kg is placed on the floor and experiences two forces - a 50 N force pushing from the right and a 55 N force pushing from the left. What is the magnitude of the table's acceleration?

✓ Correct answer: A. 0.05 kg-m/sec²To determine the table's acceleration, you need to calculate the net force acting on it. The net force is the sum of all forces, taking into account that the forces in this scenario oppose each other, with the left force being positive and the right force negative.
Net force = Left force + (-) Right force
Net force = 55 N + (-) 50 N
Net force = 5 N
The net force is found to be 5 N to the left. Next, you can calculate the acceleration's magnitude using Newton's second law equation:
Force - (mass)(acceleration)
5 N - (110 kg)(Acceleration)
Acceleration = 5/110 kg-m/sec²
Acceleration = 0.05 kg-m/sec²
