Question

A car starts from rest and attains the
speed of 1 km/hr and 2 k.ms/hr at the end
of 1st and 2nd minutes. If the car moves
on a straight road, the distance travelled
in 2 minutes is
​

Answer 1

Answer:

Given: Time = 2 mins

= 1/30 hr

v= 2 km / hr

u= 1 km/ hr

therefore,

s= ut + 1/2at²

s= 1 x 1/30 + 1/2 x 1 x 1/30

s= 1/30 + 1/60

s= 2+1/60

s=3/60

s= 1/20

s= 0.05 km
