Peter wants to modify the formula for acceleration
i.e., a = (v – u)/ t
Where v = final velocity, u = initial velocity, t= time, a = acceleration, to suit the special case of freefall of a ball dropped from the top of a building. He chooses to make the following substitutions in the formula.
a. v= 0
b. u= 0
c. a= 9.8 m/s2
Identify the correct substitutions.
