Question

The displacement versus time graph for a body moving in a straight line is shown in figure. Which of the
following regions represents the motion when no force is acting on the body​

Answer 1

Answer:

c) cd

Step-by-step explanation:

force = mass * acceleration

for force to be zero acceleration must be zero as mass cannot be zero

acceleration is defined as rate if change of velocity

at the region c we get a straight line as slopewhich denotes velocity is constant

since velocity is constant acceleration in this region is zero and so force is zero

hope it helps
