Step-by-step explanation:

A ball is thrown starting at a time of 0 and a height of 2 meters. The height of the ball follows the function as follows:

[tex]H(t)=-4.9t^2+25t+2[/tex]

We need to find the height of the ball from 0 to 5 seconds

At t = 0 s

[tex]H(0)=-4.9t^2+25t+2\\\\=-4.9(0)^2+25(0)+2\\\\=2\ m[/tex]

At t = 1 s

[tex]H(1)=-4.9t^2+25t+2\\\\=-4.9(1)^2+25(1)+2\\\\=22.1\ m[/tex]

At t = 2 s

[tex]H(2)=-4.9t^2+25t+2\\\\=-4.9(2)^2+25(2)+2\\\\=32.4[/tex]

At t = 3 s

[tex]H(3)=-4.9t^2+25t+2\\\\=-4.9(3)^2+25(3)+2\\\\=32.9\ m[/tex]

At t = 4 s

[tex]H(4)=-4.9t^2+25t+2\\\\=-4.9(4)^2+25(4)+2\\\\=23.6\ m[/tex]

At t = 5 s

[tex]H(5)=-4.9t^2+25t+2\\\\=-4.9(5)^2+25(5)+2\\\\=4.5\ m[/tex]

t =  0         1                2                3                4                 5

H = 2       22.1         32.4         32.9           23.6           4.5
