Question

A football is kicked on flat ground at velocity 15 meter per second at an angle of 30 degree how long it will

be in the air

Answer 1

The football will be in the air for 1.529 seconds.

Step-by-step explanation:

Here is what we know.

Initial Velocity - 15 m/s

Launch Angle - 30°

Gravity - 9.81
`m/s^2`

Initial Height - 0 m

We can use the equation.

`t_(tot)=(2(v_(0)sinA) )/(g)`

Substituting our values into the equation gives us

`t_(tot)=(2(15sin30) )/(9.81)`

`t_(tot)=(2(15*(1)/(2) ) )/(9.81)`

`t_(tot)=(2(7.5) )/(9.81)`

`t_(tot)=(15 )/(9.81)`

`t_(tot)=1.529`
