Example 6
A car begins to move from rest. The velocity of the car increases at a rate of 4 ms-2. Find the distance traveled by the car after 12 second.
Answer:
It's advisable to list down all the information that we have.
Initial velocity, u = 0 (Because the begins to move from rest)
Acceleration, a = 4 ms-2 (Rate of increment = Acceleration)
Time taken, t = 12s
Displacement, s = ?
The final velocity, v, is not involved, hence we select the equation \(s = ut + \frac{1}{2}a{t^2}\) to solve the problem.
