Question

The ratio of the times taken by a body moving with uniform acceleration in
reaching two points P and Q along a straight line path is 1:2. If the body
starts from rest and moves linearly, the ratio of the distances of P and Q
from the starting point is​

Answer 2

Answer:

1:4

Explanation:

The ratio of time taken is 1 :2, 

The ratio of time taken is 1 :2, Using s=ut+21gt2, 

The ratio of time taken is 1 :2, Using s=ut+21gt2, The ratio of distance s2s1=21gt2221gt12=t22t12,      ( u=0 given)

The ratio of time taken is 1 :2, Using s=ut+21gt2, The ratio of distance s2s1=21gt2221gt12=t22t12,      ( u=0 given)⇒s2s1=41.
