Answer:

When a spring balance has been used for a long time, the spring in the balance fatigued and there is loss of strength of the spring. In such a case, the extension in the spring is more for a given load and hence the balance gives wrong readings.

how you could calculate a time step (dt) if you have a vector of accumulative distance (ie the distance keeps adding every step)
lakkis [162]

Answer:

dt = ds/dv.

Explanation:

to calculate the time step if you have a vector of accumulative distance and instanteneous velocity vector can be expressed bellow

solution

ds = dv/dt

divide the step distance by the instantaneous velocity you will get the time step.

that it

dt = ds/dv.

so to calculate the time step having a vector that keeps adding every step and speed at that moment is this dt = ds/dv.
