Physic lab report

hi i am mechanical engineer and gone three all questions in the report (1) In this experiment, we assumed that momentum was conserved. Is this a valid assumption? Why or why not? 2) In this experiment, we assumed that energy was conserved. Is this a valid assumption? Why or why not? 3) What are the possible sources of error in this experiment (be detailed and specific)? 4) Comment on the values of percent difference between the two calculated values of the initial speed of the projectiles. How were your results? How might you change the experiments to lower the percent difference in your values? Which of the two methods of calculating the initial speed of the projectile is more likely to be accurate? ) i am confident to do all of them thanks

Hi there, i am a masters engineering graduate with good exposure to physics and i assure i can handle the task with good care... Will deliver it in 1 day..

I have completed many physics and engineering reports of this nature. Those reports typically cover conservation of momentum, energy, and other similar concepts. I can get this done within a day.

After you hire me I'll answer to all questions. Now I answer to the two first ones. 1) In this experiment, we assumed that momentum was conserved. Is this a valid assumption? Why or why not? Yes, we can neglect gravitational force and consider the system ball+pendulum as isolated from external forces. 2) In this experiment, we assumed that energy was conserved. Is this a valid assumption? Why or why not? The shock is inelastic. During the shock the energy is not conserved. After the shock the pendulum moves in gravitational field and the energy is conserved,

It has always been a pleasure for me to teach and help students in developing critical and analytical understanding. I am proficient and experienced in engineering mechanics, physics, statics, mathematics, statistics and computational techniques. Quality work, timeliness and value for money are few things you can confidently count on me. If it is convincing, accept my bid right away, if not, move to others and I wish you good luck.
