Suppose you are an engineer, and you are asked to measure the force on a supporting beam of a bridge. You measure it to be 50,067 lbs, but you know that your scale is only precise to ±400 lbs. How do you record this measurement in your final report to the client? (Keep in mind that you want to find the perfect way to express the number to give an idea of how precise it is.) Click the above link to submit a three sentence description, which includes: (5 pts) How you would record the measurement in the final report. (5 pts) Why you would record it that way.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s. a. determine jay’s mass. b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.

Which system of units is used by only a small number of countries in the world, including the u. s.
