When the speed of car is doubled then what will be the braking force of the car to stop it in the same distance ? (a) four times (b) two times (c) half (d) one fourth
Option a. Brake pressure, additionally called Brake Power, is a degree of braking strength of a vehicle. Suppose a automobile whose mass is ‘x’ and is braked from a velocity of y km/hr to return back to halt at a uniform retardation in z min. If the rate of the automobile is doubled withinside the identical distance, then the braking pressure required to forestall the auto is 4 instances the unique velocity i.e. ‘4v’. Note that each one the parameters stay to be identical.
