Question

A 0.64-kg block sits on a lab table. There is a forward force of 1.98 N and a force backwards of 0.79 N. What is the acceleration of the block?

Answer 1

The acceleration of the block is 1.22 m/s².

Step-by-step explanation:

To find the acceleration of the block, we need to use Newton's second law of motion. This law states that the acceleration of an object is equal to the net force acting on it divided by its mass. In this case, the net force is the forward force minus the backward force. We can plug in the values into the equation to find the acceleration:

acceleration = (forward force - backward force) / mass

acceleration = (1.98 N - 0.79 N) / 0.64 kg = 1.22 m/s²
