Both of those did not work. I am just glad that I understand what I am doing because when the program told me I was wrong I got very confused. I will try to email my professor, thank you for your help!

The online homework program I am using (Pearson) says that the answer is wrong.

Now, because it is a projectile in free fall and there are no forces acting on it in the x direction, I am assuming that my acceleration in the x direction is zero. Therefore I am using the equation : (x-xo) = voxt + (1/2)axt^2 (x-xo) = (1.98)(0.1969) + (1/2)(0)(0.1969)^2 (x-xo) = 0.3899 m OR...

For this I used the equation : (y-yo) = voyt + (1/2)at^2 (-0.19) = (0)t + (1/2)(-9.8)t^2 t = 0.1969 s Because I am given the acceleration due to gravity, the distance in the y component, and the initial velocity in the y direction being zero.

That does all make sense, that's what I tried to do (and thought I did). It takes the same time to hit the ground because there are no forces in the y direction (except for gravity) that would make the ball it the ground faster and the x component does not affect the y. I tried to use the ac =...

I edited the forum now, and I thought the acceleration of the ball would be zero, therefore having a constant velocity, after it was released.

Homework Statement A 60 g ball is tied to the end of a 40-cm-long string and swung in a vertical circle. The center of the circle is 150 cm above the floor. The ball is swung at the minimum speed necessary to make it over the top without the string going slack. If the string is released at the...
