ok, i got this one while watching some random movie. Everytime the brake of some 4 wheeler fails, the person tries to stop it by hitting it onto some object, now, the thing bothering here is that isn't there anyother way to stop it ? well, i thought of 3 probable ways, are these actually valid for a RWD car? 1. Disengage the clutch fully and allow the vehicle to be freewheeling until the frictional force on the tyres tries slowing it down with small decrease in speed. 2. Disengage the clutch and shift the passengers of the car to the front, in this way, the total momentum on the driving axle would be more and hence, the load carried by the vehicle increases, this inturn has a greater slowing effect than the previous case. 3. Put the vehicle on reverse gear and slowly try engaging the clutch at intervals.. and trying to control the speed purely by the friction developing . The anticlockwise rotation here may try to cause some sparking or over heating under the vehicle, but it should be a good try. are these things actually valid ?
