Afootball is kicked from ground level at an angle of 38 degrees. it reaches a maximum height of 9.7 meters before returning to the ground. how long will the football spend in the air, in seconds?

Football will be in air for 2.8139 sec

Explanation:

We have given maximum height h = 9.7 meters

Angle of projection

We know that maximum height is given by

So

u = 22.396 m/sec

Time of flight is given by

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

god i hope this !
