8) Two blocks with masses my = 0.820 kg and m2 = 1.40 kg are connected by a string as shown in the figure. If k = 0.200 for the horizontal surface, find the acceleration. I need to draw picture and show all work please
Draw a picture Label which directions are positive (x- and y-), and label relevant quantities on diagram Find a second equation... ...if you're missing a quantity needed to use an equation. Draw up a plan on how to link the equations & quantities Solve for the quantity without using numbers Physics Problem Flow Chart Draw a second picture... Identify explicitly given values First cancel any quantities that are zero. Use algebra to isolate the quantity you need on one side of the equals sign. Check with dimensional analysis ...if you have BEFORE/AFTER situations, force additions, vector component diagrams Find relevant equation(s) One that links the given quantities to the quantity you need to find Sub in numbers on paper Make sure units of each number are correct before you substitute in values into the equations Write all given actual numbers in terms of variables. For previously calculated values, use values before rounding for sig figs Identify required quantity and type of problem Look for keywords like "when", "how far", "how fast", etc. Get type of problem from quantities given/sought Use calculator to find value Use as few presses of the "=" or "ENTER" button as possible. Keep extra sig figs until next step Identify implicitly given values Wording that implies specific values: e.g. "at rest", "comes to a stop", "dropped", "smooth surface", "constant velocity" Calculate/convert easily derived quantities For example, the x- and y- components of velocity/force vectors, or the force of gravity given the mass Write conclusion statement with correct sig figs In plain English with correct units
