Question
A bus moves in such a way that its velocity increases by 9 m/s every second. What is its acceleration?
- = 9 m/s2
- < 9 m/s2
- > 9 m/s2
- 0
Hint:
= 9 m/s²
The correct answer is: = 9 m/s2
Given:
Initial velocity = 0ms-1
Final velocity = 9ms-1
Time taken = 1s
To find:
Acceleration =?
Solution:
Acceleration = change in velocity / time interval

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.
