A and B are thrown vertivally upward...

A and B are thrown vertivally upward with velocity 5m/s and 10 m/s respectively `(g=10 m//s^2` ) . Find separtion between them after one second .

Verified by Experts

`S_A = ut -1/2 g t^2 = 5 t -1/2 xx 10 xx t^2 = 5 xx t^2 = 5 xx 1 -5 xx 1 ^2 =5-5=0`
` S_B = u t -1/2 g t^2 = 10 xx 1 -1/2 xx 10 xx 1^2 = 10- 5 =5`
` therefore S_B - S_A ` = separtion = 5m.
