Mass=2.20

T=10
Friction=0.400
Determine the acceleration when x=0.400m

To determine the acceleration when x = 0.400m, we can use Newton's second law of motion. The equation is stated as follows:

a = (F - F_friction) / m

Where:
a = acceleration
F = applied force
F_friction = force of friction
m = mass

In this case, the mass is given as 2.20 kg, and the force of friction is given as 0.400. However, the applied force (F) is not mentioned, so we cannot directly calculate the acceleration with the information provided.

If you have any additional information about the problem, such as the applied force or any other relevant details, please provide it so that I can assist you better in finding the acceleration.
