Select the correct answer. a ball is thrown straight down from the top of a building at a velocity of 16 ft/s. the building is 480 feet tall, and the acceleration due to gravity is 32 ft/s2. this problem can be represented using the following equation. how much time will the ball take to reach the ground

The ball takes 5s to reach the ground

Explanation:

in order to solve this problem we use the kinematics equation with gravity as acceleration:

we replace the values

We solve this quadratic equation:

t=5s

t=-6s   (this solution has not physical sense)

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
