height velocity children

of a projectile motion problem?
a girl throws a water balloon at an angle of 50 degrees with the horizontal component and speed of 12m / s. A car in the right moves to the right with speed of 5.35 m / s away from the child. The ball hits the front of the car to the same height at which leaves of the child's hand. A.) What is the distance D traveled by the car while the ball is in flight? b) What was the distance D 'between the front the car and the child, when he launched the balloon?
flight time = t = 2 * v * sint / g = 12 V g = 9.8 t = 50degrees t is the projection angle therefore, the distance traveled by car D = 5.35 * The total distance t horizontal covered by ballon R = v ^ 2 * sin (2t) = G D + D '= RD' RD
Height growth treatment
Since you found this site, I assume you are interested in gaining a few extra inches of height. Although (if you’re a mature adult) this may sound like a pipe dream, I assure you that it is easier than you think! We’ve all been taught that height is mostly out of our control, that it’s largely determined by genetics. I’m here to tell you that there is more to the story. Of course our gene pool has a lot to do with ones height, but it is definitely not the only factor. Your state of emotion, your exercise regimen, the food you eat, and the hours you sleep are all factors in height determination. Click here to read the rest of the article: Free Height Enhancement
