Question

a car is travelling with a velocity of 27ms¹ when brakes are applied it undergoes a uniform retardation of 1.2ms what will be the distance covered by the car before it stopped​

Answer 1

Explanation:

given,

u = 27 m/s

v = 0 m/s

a = 1.2 m/s*2

since,

2as = v*2 - u*2

therefore,

=> 2×1.2s = 0*2 - 27*2

=> 2.4s. = 0-54

=> 2.4s. = -54

=> s = -54/2.4

=> s = -22.5 km
