This picture is of a swimming backstroke start. It represents projectile motion because of the parabola shape. In this case the parabola is opening down. For a backstroke start the arched back with the feet following up on the whole body's motion creates the parabola. Right at the beginning the first push the velocity 9.8m/s and continues until the peak of the start where the velocity it Om/s because she is not going up or down. Then eventually starts going down with the velocity again at 9.8m/s.
This tiger leaping is just one example of a projectile's motion. A projectile's motion first goes up and then eventually comes down, because everything has a velocity of 9.8m/s. The tiger's initial velocity is 0 m/s, because he was at rest before he leaped into the air. Once he's in the air his velocity changes every second by 9.8 m/s. Then when the tiger reaches it's peak it has a velocity of 0 m/s for that one second becasue he is neither falling or going up. Then the tiger's velocity changes by 9.8 m/s again until it lands on the ground.
