A top of a basketball net is $2\mathrm{.}5$ m above the ground. A basketball player jumps and shoots the ball at a point $2\mathrm{.}8$ m above the ground and a horizontal distance of $8$ m from the basketball net. The initial speed of the basketball is horizontal and equal to $20$ m$/$s$.$ Using kinematics equations, determine the height of the ball when it reaches the net. Please explain each step of this problem in detail I$\text{'}$m kind of confused, thank you!
