Question

A figure shows the speed time graph of particle find the distance travelled in time interval 0 to 40 second

Answer 1

Answer:

Here is a small trick for you to solve these questions easily. In graph analysis we know that only area and slope gives us meaningful values.

So divide the x and y axis quantities to get the new quantity like velocity time graph

just divide velocity = LT ^ -1 / T

We will get acceleration

similarly

X - t graph will gives velocity and it is always obtained by area but we have to calculate only distance traveled

Distance travelled will be = 10 + 10 = 20 m

hope these will help you....
