Question

I need to use Newton's second law to calculate the acceleration of a box and record the value. I must use a=Fnet/m; my numbers are 150N Fapp(N); 94N FFr(N); Sum of Forces 56N, and I think my accelaration time (m/s^2) is 39.8. I'm not sure if my time is correct, because I was looking when the simulator completed the task. Please help me calculate this problem, I am very new to Physical Science and I don't know what I'm doing. Please , please help.

Thank you!

Answer 1

You need to note the mass of the box.

To calculate the acceleration of the box using Newton's second law, we can use the formula:

a = Fnet / m

Where:

1. a is the acceleration (in m/s^2)
2. Fnet is the net force acting on the box (in N)
3. m is the mass of the box (in kg)

Given the following values:

1. Fapp = 150 N (applied force)
2. FFr = 94 N (frictional force)

To determine the acceleration (a), we need to use the following equation:

Fnet = Fapp - FFr

Fnet = 150 N - 94 N

Feet = 56 N

Now we can calculate the acceleration through the equation:

a = Fnet / m

a = 56 N / m

once you substitute the value of m you should get your acceleration value in m/s^2
