okay i got it thank you so much i had my signs all wrong thank you again!

physics
it's still wrong :( i've tried my way and your way and it's still wrong

physics
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?

physics
Well so to convert k constant to N/m would it be 22 N/m instead of 2.2 N/cm?

physics
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.

algebra
the function H described by H (x) -2.75x+71.48 can be used to predict the height in centimeters of a women whose humerus is z cm long predict the height of the womens humerus is 32 cm long

physics
A dart gun is fired while being held horizontally at a height of 1.38m above ground level, and at rest relative to the ground. The dart from the fun travels a horizontal distance of 7.76. A child holds the same gun in a horizontal position while sliding down a 28.8 degrees inc...

trig
Given that tan 45=1, use tan(x+y) to show that tan 22.5= /2 - 1. (/is square root sign
