Question

Could someone help me solve!

A projectile is fired from the origin with an initial velocity V1=1130 m/s at an angle (theta)1=2.5 degrees from the horizontal while another is fired at the same instant from a point on the x-axis at a distance 199 m from the origin with an initial velocity V2=120 m/s at an angle of (theta)2. It is desired that the two projectiles collide.
a) determine the value of (theta)2
b)at what time and at what point do they collide
