Question
A racing car has a uniform acceleration of 4 \text{ m s}^{-2}. What distance will it cover in 10 \text{ s} after start?
Answer
Given:
Initial velocity (u) = 0 (starts from rest)
Acceleration (a) = 4 \text{ m/s}^2
Time (t) = 10 \text{ s}
Formula:
s = ut + \frac{1}{2}at^2
Calculation:
s = (0 \times 10) + \frac{1}{2} \times 4 \times (10)^2s = 0 + 2 \times 100s = 200 \text{ m}
Answer: The car will cover a distance of 200 \text{ m}.
