A motorcycle is travelling in a straight line at 150km/hour, and brakes to bring it to rest in 4.5 seconds. The road wheels have an effective radius of 340mm. Determine the number of revolutions made by the wheels in the total braking time. [Please provide solution and Answer, much appreciated]
They remove oxygen or block access to oxygen. Fire needs oxygen.
I'm not an expert but I think it's depriving the fire of oxygen, suffocating it, if you will.
150 km/h 41.666. m/s assuming braking force is constant, the acceleration on the motorcycle is 41.666./4.5 9.259259. m/s? distance travelled ut + 1/2 at? 41.666. * 4.5 + 0.5*9.259. *4.5? 281.25 m number of rotations 281.25/(2*pi*0.34) 281.25 / 2.136 131.7 rotations (4 sf)
