what does this mean. I am performing an experiment on an air track with a cart that experiences significant air resistance. For this experiment i think i need to assume it goes at a constant speed. I am supposed to design a method that will allow me to calculate a corrected value with 2...
The answer is in radians 360 = 2pi the negative would be that it is in the clockwise direction. but how can i get rid of A by dividing they are different equations
isolating A then making the equations equal results in the same answer.
the answer i got was phi = 1.04748404 rad which is ~ -pi/3
well i just realized that A = x/cos(phi) therefore when you sub that into velocity you can get sin(phi) / cos(phi) which = tan(phi) therefore you can solve for phi however the answer that i get is only 1/2 the answer in the textbook which is -2pi/3.
oh.. srry my bad i typed it wrong ill edit it now.. but when i solve for phi in each equation then make them equal i get like
sin^-1[\frac{V_x}{A\omega}] = cos^-1[\frac{x}{A}]
I can't get A out from there like if i make one side [\frac{V_x}{A\omega}] or [\frac{x}{A}] the other side becomes...
well technically the t isn't there since t = 0 wt = 0 therefore the new equation becomes
Acos(\varphi) = x(t) and V_x(t) =-\omegaA(\varphi) and i didnt differentiate the x(t) formula into the v(t) one they were given by the textbook
Homework Statement
An air track glider attached to a spring oscillates with a period of 1.5s AT t= 0s the glider is 5.0 cm left of the equilibrium position and moving to the right at 36.3 cm/s
so from what the question i have determined that T = 1.5s x= -0.05m V_x = 0.363m/s
t = 0

[SOLVED] Cyclopentane to Cyclohexane
i was assigned a question where i started out with a cyclopentane in the reactants that became a cyclohexane. What possible reaction mechanism could have taken place to form a cyclohexane from a cyclopentane?
I am doing a question that goes like this Lim of sqrt(x) * sine(1/sqrt(x)) as x --> infinity = ? what i determined was as x --> infinity 1/sqrt(x) would approach zero there for sine of 1/sqrt(x) would approach 1 there fore 1 * sqrt(infinity) would be infinity. however the answer says it is 1...
I have no clue where to start on this question.
Use Cartesian vectors in two-space to prove that the line segments joining midpoints of the consecutive sides of a quadrilateral form a parallelogram.
Atm all i can deduce from the information is that vectors 2A+2B+2C+2D=0 therefore midpoint...
