A group of students launch a paintball cannon from the back of a stationary truck, parked on a 30 incline as shown. The paintball cannon is a height h- Im off the incline. The cannon fires paintballs up the hill with initial velocity of 30 m/s relative to the truck and at an angle 20 relative to the inclined plane as shown. A lone student is running down the incline, initially 50nm from the back of the truck. The paintbal hits him in the chest, 0.5m off the ground What is the distance between the truck and the paintball the moment the paintball hits the student?
