Today I decided to clean my room, because people where coming to my house. I started by taking the clothes off the ground and putting them away. Then I began to clear my desk from all the empty water bottles and random pieces of paper. I started launching them into the trash can. I realized at that moment that I was making a projectile with the balls of paper I was throwing. The crumpled piece of paper's horizontal velocity remained the same. However, because of the gravity (-9.8m/s²) the ball of paper falls after reaching its maximum height and gains velocity in the negative direction. When the ball of paper reaches its maximum height, its velocity is zero. In order to find the initial velocity, I must measure change in Y or vertical displacement. I also need to find the time it takes for the paper to reach the trash can after it is released from my hand Once I find those values I can plug it into this equation: ▲y=Viyt + 1/2at² to find the initial velocity.

wow! how'd you take a picture with the paper in the air? that must've been quite difficult.
you should have recycled that paper >:0
