Engineers are designing a system by which a falling mass mimparts kinetic energy to a rotating uniform drum to which it isattached by thin, very light wire wrapped around the rim ofthe drum (Figure 1). There is no appreciable friction in theaxle of the drum, and everything starts from rest. This systemis being tested on earth, but it is to be used on Mars, wherethe acceleration due to gravity is 3.71 m/s?. In the earthtests, when m is set to 15.0 kg and allowed to fall through3.00 m, it gives 350.0 J of kinetic energy to the drum.Part AIf the system is operated on Mars, through what distance would the 15.0 kg mass have to fall to give the same amount of kinetic energy to the drum?Express your answer with the appropriate units.HAhM =ValueUnitsPart BFigure1 of 1How fast would the 15.0 kg mass be moving on Mars just as the drum gained 350.0 J of kinetic energy?Express your answer with the appropriate units.DrumHAValueUnitsv =

A point charge q1 = +5.00 micro Coulomb is held fixed in space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00 x 10-3 kg and charge q2 = +2.00 micro Coulomb is fired toward the fixed charge with an initial speed of 40.0 m/s. Gravity can be neglected. What is the acceleration (in m/s2) of the sphere at the instant when its speed is 25.0 m/s?

Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)
