David drops a ball from a bridge at an initial height of 100 meters. 1. What is the height of the ball to the nearest tenth of a meter exactly 3 seconds after he releases the ball? 2. How many seconds after the ball is released will it hit the ground? I have 3 questions, and I answered the first two just fine, but this kind of stuff my brain just can't get. So if you could explain it with your answer, that would be amazing. This has to be solved using h(t)= 1/2gt^2+v0t+h0I know that the v0 is 0, because there's no force given, and that g is -9.8 m/s^2 because it's meters being used, and I'm pretty sure h0 is 100, I just don't know how to put it all together, or where the 3 seconds after he releases the ball is supposed to go. Thanks for any help, and whoever answers correctly, I have either 10 or 15 points for you! (I think I might have pressed 15 but it could have also been 10 and it won't let me go back and look)
