brakes applied to car produce a uniform retardation of 90 cms^2 if the car was traveling with the velocity of 27 ms^1 then what distance will it cover before coming to rest |
|
Answer» ong>ANSWER: Explanation: Given : a = -0.9m/s² (because its retardation) v = 0 (Because in the final, the car stops) u = 27m/s (its ALREADY given) To find : Distance 'd'
Solution : The formula we will be using is - V²=U²+2as So, (0)²= (27)²+2(-0.9)(s) 0 = 729 +( -1.8)(s) => 1.8s = 729 => s = 729/1.8 So, the answer is s = 405 metres |
