Example 7: Do r = 2 cos(t) and and y = 2 sin() x + y = 4 I = 1 + cos(2t) and collide? y = 2 + sin(2t) ( 2 - 1 ) + 14-2) "= 1 - P. (0,2 ) START . Their paths cross twice. P2 Do they collicke ? 2 P, : whin t= I 2 Second particle at P, whin 2 = y= 2 +sit -> sin2t=0 0 = 2( = 1 + wslat) -> ws ( 2+ )=-) 2t = IT t = TT/2
