3rd grade math
out of 40 crayons in two boxes,one box has 8 more crayons than the other.
okay i got it thank you so much i had my signs all wrong thank you again!
it's still wrong :( i've tried my way and your way and it's still wrong
well since there's an x component of the gravity wouldn't that affect the force of friction? For my force i got (0 = theta) mgsin0 - (mu)mgcos0 is that wrong?
Well so to convert k constant to N/m would it be 22 N/m instead of 2.2 N/cm?
A spring with a spring-constant 2.2 N/cm is compressed 28 cm and released. The 4 kg mass skids down the frictional incline of heigh 43 cm and inclined at a 22 degrees angle (g = 9.8 m/s^2) The path is frictionless except for a distance of 0.9 m along the incline which has a co...
two eqtns....X+12=Y;AND X+Y=40......fromX+12=y thenX+X+12=40;2X+12=40 THEREFORE X=14....IF X=14 AND X+Y=40,THEN Y=26ANS...26DOLLARS FOR SWEATER.
