water blog post carolyn and Mack

while the water first goes up into the air, gravity pushes the water down. once it reaches its peak gravity pull the water back down with a acceleration of 9.8m/s until it reaches the bottom of the drinking fountain in this picture for example

The motion Wile E. Coyote does that is impossible is that he keeps a constant speed while traveling over a distance of 490 meters while going up and down hills and making turns left and right. Since it was obvious that he kept a constant speed, we tried to find the distance by using the distance formula. We used d=4.9m/s squared*10 seconds and found taht it was 490 meters, which is too long of a distane to complete with a consistant velocity and in 10 seconds.

Projectile motion photo post

This photo illustrates projectile motion by the water going up at a rate and hitting the top at a velocity of 0 and then falling back down at the same rate as it went up. During all of this, the water is shooting outwards instead of going up. It went up, the water would go up and fall down onto itself which doesn't make a projectile motion.

In the video Wile E. Coyote jumps off the cliff. usually when you jump off something you go down right away. However, Wile is horizontal for the whole time. the problem with this is that there is gravity which will acceleration will go up 9.8 every second when jumping off a cliff or anything for that matter. with the equation for distance d=-4.9*t^2, if Wile's jump was correct he would not be able to stay horizontally stable for that long.
