A car moving with a speed of 50 km/h, can be stopped by brakes after atleast 6 m. If the same car is moving at a speed of 100 km/h, the minimum stopping distance is |

Answer» 12m Final speed `NU=0` Using equation of motion `nu^(2)-u^(2)=2as` `a=-(u^(2))/(2s)=-(1)/(2)((500)/(36))^(2)xx(1)/(2)=-16m//s^(2)` If `u = 100 km//h=2xx(500)/(36) ` m/s = 27.78 m/s `s= (u^(2))/(2A)= ((27.78)^(2))/(2xx16) = 24m.` |
