Question

Example 3. A body travels from A to B at 40 ms -1 and
from B to A at 60 ms. Calculate the average speed and
average Velocity
​

Answer 1

Answer:

<br> total time taken by a body in going from (A) to (B) and then from (B) to (A) is ltbRgt ` t_1 + t_2 = ( AB)/(40) + (BA)/(60) = AB [ 1 /( 40 ) + 1/( 60) = ( AB) / ( 24) = x/( 24) s` <br> Total distance coverd, ` S= x + = 2 x` <br> Average speed ` = S/( t_1 + t_2) = ( 2 x)/( x// 24) = 48 ms^(-1)` Displacement of the ...
