yeah gotit!!!!!
this is the original doubt i had!!
i tired it but i got ans as 1.3 sec wheas in proving it must be 1.8!!!
help!!
alien Spacecraft:
-> (12j) + (40i + 15j)(t)
=> (40t)i + (12 + 15t)j
the missile
=> (46i) + (ki +30j)(t-0.5)
=> (46 + k(t - 0.5))i + (30(t-0.5))j
t has to be t - 0.5 here because it left 0.5 seconds after the alien spacecraft
(40t)i + (12 + 15t)j = (46 + k(t - 0.5))i + (30(t-0.5))j
12 + 15t = (30(t-0.5))
12 + 15t = 30t - 15
27 = 15t
t = 1.8
@shrey - sry, that is 240
300 and 40 ..i got it from the vector Vp
