WBJEE · Physics · Motion In One Dimension
Figure below shows the distance-time graph of the motion of a car. If follows from the graph that the car is
- A at rest
- B in uniform motion
- C in non-uniform acceleration
- D uniformly accelerated
Answer & Solution
Correct Answer
(D) uniformly accelerated
Step-by-step Solution
Detailed explanation
Slope is increasing with constant rate. i.e motion is uniformaly accelerated \(\mathrm{x}=1.2 \mathrm{t}^2 \Rightarrow \mathrm{v}=2.4 \mathrm{t} \Rightarrow \mathrm{a}=2.4 \mathrm{~m} / \mathrm{s}^2\)
