How fast will a ball be falling after 15 seconds

it depends on how high up u dropped the ball if the ball was only taking 15 seconds to hit the ground then the ball couldn't go any faster cause its done landed but if the ball was falling 20 mph then there is a chance that it would go 25mph landing compared to when it first fell

plz mark me the brainliest

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
