Question
A body moving at a velocity of 4 m/s uniformly accelerates to a velocity of 24 m/s. Its average velocity is ___ m/s.
Hint:
14 m/s
The correct answer is: 14
Given:
Initial velocity = 4 m/s
Final velocity = 24 m/s
Solution:
The body is uniformly accelerating. Therefore, its average velocity = (24 + 4)/2 = 14 m/s

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.
