Question

please please help me with this one problem that relates to every part in here!! they all relate to each other. you need one for another. please help me i am stuck!!! thank you. it takes 4 seconds to reach the bottom of tower.

Use a coordinate system where up is positive and the origin is at the bottom of the tower.

Use the values from the previous questions and the height equation y = yo + voyt - gt² to find the number of seconds it takes for the ball to drop to the bottom of the tower. Round your answer to 2 significant figures and enter it into the box below. (Just give the number, without the units.) To check your answer, compare what you calculated with what you estimated from the video. If they aren't relatively close (within about 1 second), you may not have calculated the correct time. Question 5 Using the time you found in the previous question, calculate the speed (in m/s) at which it hits the water. Remember that speeds are not negative numbers. Round your answer to 2 significant figures and enter it into the box below. (Just give the number, without the units.) Question 6 Finally, convert the speed you found from units of m/s to units of miles/hour. Round your answer to 2 significant figures and enter it into the box below. (Just give the number, without the units.)
