Question

Someone please solve this for me

Answer 1

hi you say to Google

Answer 2

gun2:fires at t=0

x direction : x =5root3 * cos 60 * (t )

y direction : y = 5root3sin60(t) - 1/2 *g *(t)2

gun1:fires at t=t1

x direction : x =5root3 *(t-t1)

y direction : y = - 1/2 *g *(t-t1)2 (negative as upward direction is positive




when they collide their x and y cordinates are equal ,

so if they collide at t=t2 then ,

5root3 *t2-t1= 5root3 * cos 60 * (t2 )

- 1/2 *g *(t2-t1)2 = 5root3sin60(t2) - 1/2 *g *(t2)2

solving we get ,

t2= 2s , t1 =1s

so 1) time interval b/w firing =t1 =1s

2)p = (5root3 *(2-1) , -1/2*g*(2-1)2 )

p =(5root3 , -5)
