Question

please tell me answer of this

Answer 1

Heres your answer

u=40 km per/h= 40×5/18=11.1 m per sec

v=0

a= -0.6 mere per sec^2

s=?

By using third equation of motion we can find distance ....

${v}^{2} = {u}^{2} + 2as \\ \\ {0}^{2} = {(11.1)}^{2} + 2 \times ( - 0.6) \times s \\ \\ 0 = 123.21 - 1.2s \\ \\ 1.2s = 123.21 \\ \\ s = 102.675m \: approx$
Hope it helps!!
