velocity of boat (vb) =15 mile per hour
=22 ft/s
velocity of man(vm)=6 ft/s
so
displacement of man with respect to boat in 1 sec(sm) =“v_mt”
“s_m=6times1=6 ft”
displacement of boat(sb)=“v_bt”
“s_b=22times1=22ft”
so displacement of man with respect to earth will be
“s=sqrt{s_m^2+s_b^2}\s=sqrt{6^2+22^2}=22.8 ft”
so displacement of man with respect to earth will be 22.8ft
