1. The problem statement, all variables and given/known data A ball is shot out of a gun with an initial speed of 110 m/s. The acceleration of ball is -6 m/s^2 as it goes up an inclined plane of 1 m, which makes a 30 degree angle with the horizontal. Once the ball reaches the top of the inclined plane, it is launched off onto another inclined plane, which makes a 30 degree angle with the horizontal. These are the questions: what is the speed of the ball the moment it is released from first inclined plane. How far does the ball go before it hits the second inclined plane? What is the time it takes the ball to hit the second inclined plane? What are the coordinates of the point where ball hits the second inclined plane? 2. Relevant equations I am very confused which equations I am able to use. I could find the ball's speed the moment if flies off the first inclined plane. I know the formula for that: V^2=V0^2+2ax. But all other formulas evade me at the moment. 3. The attempt at a solution This was a difficult problem that my professor couldn't even solve. I'm very determined to solve this problem as it is very awesome.
