These are “plug-in-the-number” type activities to familiarize yon with the equations that link the concepts of physics. They are mainly one-step substitutions and are less challenging than the Problem. ? Calculate the instantaneous speed (in m/s) at the 10-second mark for a car that accelerates at 2 m/s2 from a position of rest.

First the step Speed = Distance / time The instantaneous speed in (m/s) at 10 m/s v = v oat Where, v = 0, the mark of the car accelerates is 2 m/s 2 o = 0 + 2 m/s * (10 s) v = 20 m/s.
