Question

if you throw a ball straight up into the air at a velocity of 15 m/s you want to know how high above your hand the ball will be at exactly 2.5 sec after you released it ​

Answer 1

Assuming that gravity has not caused the ball to start falling then after 2.5 seconds the ball will be 37.5 meters in the air

Step-by-step explanation:

The ball travels 15 meters every second so for 2 seconds we would multiply 15*2=30. We have 2.5 seconds so to calculate the time traveled in half a second we would divide 15/2=7.5

Then we add 30+7.5= 37.5 meters
