Question

a bus starts from Imphal for Chassad travelling at the rate of 20km/hr.After 1and half hours ,a car starts from Imphal and travelling at the rate of 30km/hr reaches Chassad 22 minutes ahead of the bus .Find the distance from Imphal to Chassad.​

Answer 1

we will use here second equation of motion

s=ut+1/2×at^2

and for that we need acceleration so we use 1st equation of motion

v=u+at

20=30+a×82

82a=30-20

a=82/10

a=8.2

so now we can find

s=30×82+1/2×8.2×82^2

s=30028.4
