An object starts from rest at x = 0 m when t = 0 s. The object moves in the x direction with positive velocity after t = 0 s. The instantaneous velocity and average velocity are related by
- \(\frac{d x}{d t}<\frac{x}{t}\)
- \(\frac{d x}{d t}=\frac{x}{t}\)
- \(\frac{d x}{d t}>\frac{x}{t}\)
- \(\frac{d x}{d t}\) can be smaller than, greater than or equal to \(\frac{x}{t}\)
Answer
(D) d x d t can be smaller than, greater than or equal to x t
