How is the X and components and speed and distance of motion of a projectile at a given time?

the projectile was initially launched with an initial velocity of 100 m / s at an angle of 30 degrees. I found the initial x and y components of velocity as follows: Vx = 100 m / s (cos30) = 86.6m / s Vy = 100m / s (sin 30) = 50.0 m / s, I also found the maximum height of 127.42m missile that: y = (Vyo ^ 2 – V) / 2 g = ( 50m / s) ^ 2 / 2 (9.81m / s ^ 2) = 127.42 m now I am supposed to find the X and y components of the velocity after the projectile has been in motion for 7s, and displacement from horizon to 7 seconds. Can anyone shed some light as how to do this?

Since there is no force in the x direction component x of the velocity does not change from its initial velocity 86.6m / s. Since the x component does not change the distance traveled is given by the speed * time to be 86.6m / s * 7s For the y component of velocity to be finding time for the projectile to reach its maximum height with the formula for final velocity = initial velocity + acceleration (gravity) * The time is 0 = 50 + (-9.81) Once you find the time this time take the total time (7s) and subtract the time you found and then use this time in the formula you just used. It should look like this final velocity = 0 + 9.81 * time is your final velocity component y.

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
