Might just be me, but if he goes up at 0.4 then g is -9.8 because it is acting in the opposite direction. If you think about it in the direction as g is 9.8 then is acceleration is going to be -0.4.bigman8424 said:

So the second one looks good to me.

To calculate tension if acceleration is given, you can use the formula T = ma, where T is tension, m is mass, and a is acceleration. Simply plug in the known values and solve for tension.
Yes, the formula T = ma can be used to calculate tension in various situations as long as you have the values for mass and acceleration. However, in some cases, you may need to consider other factors such as friction or gravity.
For consistency, it is best to use the standard units of measurement for mass (kilograms) and acceleration (meters per second squared) when calculating tension. This will ensure accurate results and make it easier to compare with other calculations.
Yes, tension can be negative if acceleration is negative. This simply means that the force is acting in the opposite direction of the tension. However, in most cases, tension is considered to be a positive value as it represents the force pulling on an object.
No, it is not possible to calculate tension without knowing the acceleration. This is because the formula T = ma requires both the mass and acceleration values to solve for tension. If you do not know the acceleration, you will need to gather more information or use a different formula to calculate tension.
