Question

Given the following v-t graphs: Select the graph that indicates the largest amount of particle displacement between O and 3 second. 20 20 20 10 10 1 2 3 10 1y 20 20 20 10 10

Answer 1

Key point :

Area under the v- t graph gives displacement

$\dpi{150} \bg_white \rightarrow$ Now calulate area under each graph

$\dpi{150} \bg_white \rightarrow$ comapre area of each graph .....the maximum area will correspond to maximum displacement to that graph

Hence displacement of graph A, B ,C, D,E,F are as below:

S(A) =60 unit

S(B) = 30 unit

S(C)= 30 unit

S(D)= 30 unit

S(E) = 45unit

S(F) = 30 unit

From it can be concluded that particle displacement of graph A is greatest among all in a time interval of 3sec.
