Question

2. The motions of two objects, A and B, are defined
by the following vectors:
vector A = 6.0622i + 3.500j m/s
vector B = 5.9500i + 10.3057j m/s
unit vector of bullet = -j
Object A and B left at the same time and at the
same point. Object A aims to hit object B by
firing a bullet in the direction stated above after
20 seconds. What should be the velocity of the
bullet so that it will hit object B?
