371727 An object of mass \(15 \mathrm{~kg}\) moves at a constant speed of \(15 \mathrm{~ms}^{-1}\). A constant force, which acts for 5 seconds on the object gives it a speed 5 \(\mathrm{ms}^{-1}\) in opposite direction. The force acting on the object is?

371728 A car moving at a speed ' \(v\) ' is stopped by a retarding force ' \(F\) ' in a distance ' \(s\) '. If the retarding force were \(3 \mathrm{~F}\). The car will be stopped in a distance

371729 Two blocks \(A\) and \(B\) of masses \(4 \mathrm{~kg}\) and \(6 \mathrm{~kg}\) are as shown in the figure. \(A\) horizontal force of \(12 \mathrm{~N}\) is required to make A slip over B. Find the maximum horizontal force \(F_{B}\) that can be applied on \(B\) so that both \(A\) and \(B\) move together \(\left(\right.\) take \(\left.g=10 \mathrm{~m} . \mathrm{s}^{-2}\right)\)
