Question

The x-t graph shown in figure represents a) constant velocity b) velocity of the body is continuously changing c) Instantaneous velocity d) The body travels with constant speed upto time t1 and then stops ​.

Answer 1

Answer:

Explanation:

Slope of a displacement time graph gives velocity,

Since , slope is constant till T1

Therefore it represents constant velocity till T1

After T1 the slope is 0

Therefore velocity is 0 ,

So, the correct answer is d)

Answer 2

The graph in the shown figure represnts:

d) The body travels with constant speed upto time t1 and then stops .

• Constant speed - when the speed of the object remains same and does not change(increase or decrease) it is known as constant speed.

• The slope of the graph is constant till it's,

$upto \: t_{1}$

• But it will be zero after

$slope \: t_{1}$

Hence the body travels with constant speed upto time t1 and then stops .
