Sagot :

ANSWER

[tex]35.02m[/tex]

EXPLANATION

Parameters given:

Initial velocity, u = 26.2 m/s

When the vase reaches its maximum height, its velocity becomes 0 m/s. That is the final velocity.

We can now apply one of Newton's equations of motion to find the height:

[tex]v^2=u^2-2as[/tex]

where a = g = acceleration due to gravity = 9.8 m/s²

Therefore, we have that:

[tex]\begin{gathered} 0=26.2^2-2(9.8)s \\ \Rightarrow19.6s=686.44 \\ s=\frac{686.44}{19.6} \\ s=35.02m \end{gathered}[/tex]

That is the height that the vase will reach.
