One ship, sailing east with a speed of 7.5 m/s, passes a certain point at 8 AmM; and a second ship sailing north at the same speed, passed the same point at 9.30 A. M. At what time are they

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
