Question

Body A starts from rest with an acceleration 'a' after 2s another body starts from rest with an acceleration 'b' if they travel equal distances in the 5th second, after the start of body A then what is the ratio of a:b?

Answer 1

Answer:

ratio : 5:7

Explanation:

from start of A and B

A = B - 2 sec........(1)

a = b = 5 to sec

then

a= 5

b= a + 2

= 5+2

= 7 [ Form (1) ]

so, ratio = a:b

= 5:7
