Question

A uniformly accelerated bike passes through a series of a check post 1,2 ,3 ,4and 5. The distance between 1 and V check post is 360m . The bike process the check post at the successive time intervals which are in the ratio of 1 :2:3:4 . If the velocity of the bike at 1 and 5 check posts are 12 kmph and 132 kmph respectively then ,

Answer 1

Answer:

36kmph,72kmph,120kmph

Explanation:

Given that time intervals are in ratio 1:2:3:4

now speed will also be in ratio 1:2:3:4

now let the speeds be x,2x,3x,4x.

given x=12kmph

the speed should be increased by 2x hence 12+2x=36

similarly further speeds will be increased by 3x and 4x i.e.72kmph,120kmph.
