Since the object is at the top of its trajectory its change in altitude (sin velocity) should be 0. Then you just need to calculate for the speed in the horizontal axis(which never changes in simple projectile motion). It becomes 141 cos(pi/4) or 141 cos (45) if you prefer ...

Answer for a is that the path will be linear, meaning that the person will see it as a 'vertical" motion.. However, for b, the answer is that the observer will see the object motion as a parabolic or projectile motion... Hope it helps.
