Arianna kicks a soccer ball off the ground and into the air with an initial velocity of 42 feet per second. Assume the starting height of the ball is 0 feet. Approximately, how long does it take until the soccer ball hits the ground again?

Best ResponseYou've already chosen the best response.0you dont show the angle (to the ground) of that velocity, i cant work out the answer!

Best ResponseYou've already chosen the best response.0and i think we can assume dat its the vertical velocity, or the question cant be solved

Best ResponseYou've already chosen the best response.2Arianna kicks a soccer ball off the ground and into the air with an initial velocity of 42 feet per second. Assume the starting height of the ball is 0 feet. Approximately, how long does it take until the soccer ball hits the ground again? 1.3 secs 2.6 secs 16.0 secs 27.6 secs

Best ResponseYou've already chosen the best response.0well my method to solve the prob is a physical way, which needs the angle. can you tell me how to work out 2.6??

Best ResponseYou've already chosen the best response.2Yeah, how'd you get 2.6

Best ResponseYou've already chosen the best response.0Well it's more of a common sense guess becuase soccer balls don't stay in the air for 16 seconds or 27.6 and 42 feet per second is not gonna stay in the air for just one second. Also it matches up with A.Avinash_Goutham's answer.

Best ResponseYou've already chosen the best response.0Well if it is a question about when it will land it's not gonna go into the goal

Best ResponseYou've already chosen the best response.0i think da answer wud be 27.6 cos 42 feet per second is pretty fast and so it will stay in air for quite long

Best ResponseYou've already chosen the best response.0um y is it 27.6?

Best ResponseYou've already chosen the best response.0You can get that by using the formula h(t)= 16t^2+vt+s. V is the velocity ( in this case starting speed) and s is the starting elevation. You'd get 16t^2+42t=0. Then turn that into 16t^2=42t. Then divide by 16t. It would be t=2.6
