1. The problem statement, all variables and given/known data A plane, diving at an angle of 53 degrees with the vertical, releases a projectile at an altitude of 730m. The projectile hits the ground 5.0 seconds after being released. a.) Calculate the speed of the plane b.) Calculate the horizontal distance traveled by the projectile during its flight. c.) Calculate the velocity of the projectile just before it strikes the ground. Express the answer in magnitude-direction form. 2. Relevant equations 3. The attempt at a solution I dont even know where to start with this. How am I able to find the velocity of the plane? I can calculate velocity, position, acceleration, etc all day about the projectile. I have the vectors drawn up but I can't put the pieces together. I really just need a place to start.
