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 of an apple that falls freely from a rest position and accelerates at 10 m/s2 for 1.5 s.

Solution 16PC The formula for the velocity of an object travelling with constant acceleration and started from zero velocity is given by v = at Where a is the acceleration and t is the time. Now in this given problem we have a = 10 m/s 2 And t = 1.5 s Hence the velocity v is v = (10 m/s )(1.5 s) = 15 m/s So the velocity of the object after apple after 1.5 second is 15 m/s.
