Hey! Here's a a structure of a sample lab report:

<h2>Summary of Lab <u>(SUBJECT)</u></h2>

Question(s) we are trying to answer:

<em>Write question(s) here. </em>

<em>Add observations and/or previous experiments. </em>

<em />

<em>HYPOTHESIS</em>

<em />

  1. <em>prediction</em>
  2. <em>solution</em>
  3. <em>replicable proposed solution</em>
  4. <em>references (in)dependent variable(s)</em>
  5. <em>etc</em>

<em>MATERIALS</em>

<em />

<em>Make a list of all materials used in the lab. </em>

<em />

<em>PROCEDURE</em>

<em />

Write a detailed, step-by-step list (or paragraph in list format) that explains what you did in the lab.

It should be written so that somebody who's never done this can carry it out. Describe safety concerns.

It helps to have somebody test it out.

Results

Describe what happened!

Should include all data, tables, et cetera.

Label correctly!

Conclusion

Answer the following question:

Do my results support or oppose my hypothesis?

Explain why you chose what you did. Make sure it's UNBIASED.

Discuss errors.

Close out in the end.

<h2>The answer got is reasonable.</h2>

Explanation:

We have equation of motion v² = u² + 2as

Initial velocity, u = 300 m/s  

Acceleration, a = ?

Final velocity, v = 400 m/s  

Displacement,s = 4 km = 4000 m

Substituting  

v² = u² + 2as

400² = 300² + 2 x a x 4000

a = 8.75 m/s² = 8.8 m/s²

The acceleration is 8.8 m/s²

The answer got is reasonable.

A 25 kg block is held against a compressed spring and then the spring is allowed to decompress giving the block a velocity. The
Alex787 [66]

Answer:

h=18.05 cm

Explanation:

Given that

m= 25 kg

K= 1300 N/m

x=26.4 cm

θ= 19.5 ∘

When the block just leave the spring then the speed of block = v m/s

From energy conservation

\dfrac{1}{2}Kx^2=\dfrac{1}{2}mv^2

Kx^2=mv^2

v=\sqrt{\dfrac{kx^2}{m}}

By putting the values

v=\sqrt{\dfrac{kx^2}{m}}

v=\sqrt{\dfrac{1300\times 0.264^2}{25}}

v=1.9 m/s

When block reach at the maximum height(h) position then the final speed of the block will be zero.

We know that

V_f^2=V_i^2-2gh

By putting the values

0^2=1.9^2-2\times 10\times h

h=0.1805 m

h=18.05 cm
