Sam kicks a soccer ball from the ground. The height of

the ball (in feet) can be modeled with the function

h(t) = −16t(t − 2.6), where t is the time in seconds

after the ball is kicked. How long wil it take for the ball to hit the ground?

The ball will take 2.6 seconds to hit the ground again.

Step-by-step explanation:

Sam kicks a soccer ball from the ground. The height of  the ball (in feet) can be modeled with the function,  h(t) = −16t(t − 2.6), where t is the time in seconds  after the ball is kicked.

So, the ball will be at ground when h = 0 = - 16t(t - 2.6)

⇒ t = 0 or t = 2.6.

Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

one that is bigger than 3 1/2
