Question

I need help on number 5. We need to use one of the four kinematics equations.

Answer 1

`35.02m`

Step-by-step 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:

`v^2=u^2-2as`

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

Therefore, we have that:

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

That is the height that the vase will reach.
