Question #68434

A car is starts from rest and accelerated till 30 second. If the distance covered by first 10 second is x1,distance in next 10 second is x2 and distance in last 10 second is x3 , then what will the ratio of x1,x2,x3?

Expert's answer

x1=12a(10)^2=50a

x2=10a∙10 +12a(10)^2=150a

x3=20a∙10 +12a(10)^2=250a

Since,

x1:x2:x3=50:150:250=1:3:5

x2=10a∙10 +12a(10)^2=150a

x3=20a∙10 +12a(10)^2=250a

Since,

x1:x2:x3=50:150:250=1:3:5
