5. A Green projectile has an initial velocity of 20.0 m/s at an angle of 35.0° with respect to the x-direction and is initially at ground level. a) A Blue object is initially at ground level, 15.0 meters in front of the Green object. If it is launched straight upward at the same time the Green projectile is launched, what should its initially velocity be if it is to collide with the Green object? Let the Blue object be traveling upward when they collide. b) What is the velocity of the Blue object as it collides with the Green projectile? d) If the Blue object actually had an initial velocity of 50 m/s j, how long before the Green projectile is launched should the Blue object be launched if they are to collide? Let the Blue object be traveling downward when they collide. Vi=50ml
