Question

could you solve the following question in the image. And use this check list Checklist for your solution:Are all numerical values expressed to 2 significant figures or more?Are all units the appropriate metric units?Is the diagram large, clear, and well labelled?Does the diagram have a sign convention? You must design a problem with two directions.Is all the information given contained in the solution using proper physics symbols? i.e., for the unknown initial speed use v1= ?Are all numerical values substituted into the formula after the original formula is written down in symbol form?Have you followed each step of GRASP?

Answer 1

Given,

The initial velocity of the jet u=0.

The final velocity of the jet is v=230 m/s.

The time is t=20 s.

We know the acceleration is teh ratio of change in velocity to the time taken .

Thus,

$\begin{gathered} a=\frac{v-u}{t} \\ \Rightarrow a=\frac{230-0}{20} \\ \Rightarrow a=11.50m/s^2 \end{gathered}$
