1.	A tiger chases a deer 30 m ahead of it and gains 3m in 5 second after the chase began . The distance gained by the tiger in 10 second is :
Answer» 18m 20m 6m 12m Solution :If a the relative ACCELERATION then `s = (1)/(2) at^(2)` Whent = 5S, s = 3 `3 = (1)/(2) xx axx (5)^(2)` 6 = 25 a `:. a = (6)/(25) m//s^(2)` when ` t = 10s, a = (6)/(25) m//s^(2) , s = ?` `s = (1)/(2) xx (6)/(25) xx (10)^(2)` `= (1)/(2) xx (6)/(25) xx 100 = 12m` `:.`The DISTANCE gained = 12 m
