CAS & Simplify

I am using CAS to calculate physics calculations including units like meters per second and seconds.

In the second picture you can see the problem or is it a problem? Should the approx calculate further?

Hi and thanks for the quick reply

1 & 2) Usually in physics calculations you want the approx value, for example 0,33 m/s not 1/3 m/s. Though this isn't the problem.

The problem is the answer in the second picture: -41 m * 0.05 / s^2. Why doesnt CAS-calculate it to be -2.05 m/s^2 (-41*0.05 = -2.05) ?

When the answer is an integer, it shows it fine.

ps. With "=" we get the following:
