here's a clue

the velocity isn't constant as there is a slope

anonymous · Answer

for a velocity - time graph to slope up

as the slope of the graph is positive and the slope is constant

acceleration = dv/dt

slope of velocity -time graph = acceleration

acceleration = constant 

hence , the object must move with constant positive acceleration to create a straight- line velocity time graph that slopes up

Hence , this should be ,
you should move towards sensor while speeding up
