0:00 Hello everyone.

00:01 Today we have questions.

00:02 According to the question we have given such a graph given such a graph and we have go to the four questions and we go to the following one by one.

00:13 Now we go to the first part of this question.

00:16 The first part we can say we have not about the velocity.

00:20 Then we can say velocity is equals to rate of change of displacement.

00:33 And from this graph we can say the rate of change of displacement we can measure in this form also the change in y xx is divided by change in the xxxx so we use this term and we simply put these values and we get the final answer.

00:49 Now we can put these values, we can say the velocity time t is equal to 0 to t is equal to 5.

00:58 So we can say the velocity is 10 minus of minus 15 divided by 5 minus 5.

01:03 And we get the final answer of 5.

01:07 But the displacement is, but the main concept is, but displacement is, but displacement is decreasing.

01:19 So, velocity is negative.

01:24 So we can say the final answer of this question, the velocity be the negative.

01:30 It means the minus of 5 meter per second.

01:33 This is the final answer of this question, minus of 5 meter per second.

01:38 This is the first part answer.

01:40 Now we go to the second part answer.

01:44 Second part we can find out the total displacement...
