To find the distance covered by the body in the third second, we can use the equation of motion:
Distance=Initial Velocity×Time+12×Acceleration×Time2 ext{Distance} = ext{Initial Velocity} imes ext{Time} + frac{1}{2} imes ext{Acceleration} imes ext{Time}^2Distance=Initial Velocity×Time+21×Acceleration×Time2
In this case, the body starts from rest, so the initial velocity (v0v_0v0) is 0 m/s. The acceleration (aaa) is given as 6 m/s^2, and the time (ttt) is 3 seconds.
Substituting these values into the equation, we get:
Distance=0×3+12×6×32 ext{Distance} = 0 imes 3 + frac{1}{2} imes 6 imes 3^2Distance=0×3+21×6×32
Simplifying the equation:
Distance=12×6×9 ext{Distance} = frac{1}{2} imes 6 imes 9Distance=21×6×9
Distance=3×9 ext{Distance} = 3 imes 9Distance<span class="mspace" style="margi
