Question

Please solve the question below with proper reasoning

Answer 1

Answer:

velocity=

timet

∣Distancex∣

=

dt

dx

∫dx=−vdt

x=−vt+c

Hence graph shown in B is the correct option.

Answer 2

graph 1: according to the graph ,an object has two positions at the same time which is not possible practically.

2:distance traveled only increases and never decreases with time ;its a scalar quantity.

3:speed is never negative .it can only be 0 or positive. ;velocity can be negative though.

4. for this graph ,only speed is mentioned in the graph . we know that speed can increase or decrease with time..so it can be the answer.. ;)
