option (iii) , the man should take a turn with the brakes applied . the brakes reduce the speed and the turning will make it move in another direction and avoid his collision with the wall

its a very good problem. you have to find in two cases where force require dis minimum...... 1st case apply brake........

second case go around... where force applied is minimun thedriver do that............

how to find force i think i have nt tell to you..............

approve my answer....

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
