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]
A
x = Ut + \(\frac{1}{2}t^2\)
B
x = Ut
C
x = \(\frac{V^2 - U^2}{2a}\)
D
x = -\(\frac{1}{2} at^2\)
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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)
