racing car has a uniform acceleration of 8 metre per second what distance will it cover 12 seconds after the start?
Answers
Given :-
Uniform acceleration of the racing car = 8 m/s
Initial velocity of the racing car = 0 m/s
Time taken by the racing car = 12 sec
To Find :-
Distance covered by the racing car.
Analysis :-
Here we are given with the acceleration, initial velocity and the time taken by the racing car.
Using the second equation of motion, substitute the given values in the questions and find the distance covered accordingly.
Solution :-
We know that,
- s = Distance
- u = Final velocity
- t = Time
- a = Acceleration
Using the formula,
Given that,
Initial velocity (u) = 0 m/s
Time (t) = 12 sec
Acceleration (a) = 8 m/s
Substituting their values,
Therefore, the distance covered by the racing car 12 seconds after the start is 576 m.

Solution :-
We know that,
s = Distance
u = Final velocity
t = Time
a = Acceleration
Using the formula,
Second equation of motion=s=ut+ 1/2 at ²
Given that,
Initial velocity (u) = 0 m/s
Time (t) = 12 sec
Acceleration (a) = 8 m/s
Substituting their values,
12^²s=0×12+ 1/2 ×8×12 2
144s= 2/1 ×8×144
s= 8×144/2
s= 1152/2
ms=576 m
Therefore, the distance covered by the racing car 12 seconds after the start is 576 m.
