View full question & answer→- Bodies moving:
- The body $A$ is moving with constant speed of $20cm/s$.
- The body $C$ is moving with constant acceleration.
$40=40=40=40$
- Bodies covers:
- Body $C$ covers maximum distance $100\ cm$ in $3rd$ second.
- Body $A$ covers minimum distance in $3rd$ second.
- Body $B$ is moving with non-uniform acceleration and body $C$ is moving with uniform acceleration.
