Question

If you a caleate wth for t-2s staling fom yow accaleaton of 2ls an ped rest, what reach

Answer 1

To determine the final velocity based on acceleration and time, we will use the following equation:

$v_{f}=v_{i}+at$

where vf is the final velocity, vi is the initial velocity, aa is the acceleration and t is the time. in this case as part of rest vi = 0

$v_{f}=v_{i}+at \Rightarrow v_{f}=(0m/s)+(2m/s^{2})(2s)$

$v_{f}=(2m/s^{2})(2s)=4m/s$
