Which of the following equations represents the distance x, travelled by a body moving on a straight road with a constant speed? [The other symbol have their usual meanings]
- x = Ut + \(\frac{1}{2}t^2\)
-
x = Ut
- x = \(\frac{V^2 - U^2}{2a}\)
- x = -\(\frac{1}{2} at^2\)
The correct answer is: B
Explanation
For a body moving at a constant speed, the distance x traveled can be represented by the equation:
x = U t
(constant speed = zero acceleration)
