Hello I need help answering part k. The value I used for the initial y value was 0.5m when solving for time, however my answer is wrong. I believe I am using the wrong value. I need help solving for change in time using a kinematic equation.
Correct! 8% Part (b) Sum the x-components of the force vectors. Assuming the x-direction is to the right, symbolically find all the components of the force vectors off the free-body diagram, then enter the symbolic net x force, in terms of given quantities and variables available in the symbol palette. If the symbolic net x force is zero, pick "Zero" in the palette (do not use the numeric pad). Fnet = Zero . Correct! 8% Part (c) Sum the y-components of the force vectors. Assuming the y-direction is up, symbolically find all the components of the force vectors off the free-body diagram, then enter the symbolic net y force, in terms of given quantities and variables available in the palette. If the symbolic net y force is zero, pick "Zero" in the palette (do not use the numeric pad). Fnet = Fe -F V Correct! 8% Part (d) Apply Newton's 2nd Law in x. The symbolic acceleration in x should be used to replace Fret, in the symbolic Fret, equation. Since the acceleration is not given, we can solve the symbolic Fnet equation for the x-acceleration. If the symbolic x acceleration is zero, pick "Zero" in the palette (do not use the numeric pad). 2 = Zero Correct! 8% Part (j) Set up the kinematics y-givens table for computing the y-unknowns (since we don't know enough of the x-givens yet). Which of the five kinematics givens are knowns at this point? Select all that apply. Why: 4X, By V Correct!* 8% Part (k) We see that the y-givens table will help us fill in the x-givens table because after we compute the y-table At, we can copy it to the x-table At. Pick an appropriate equation of kinematics for the y-table and use it compute the amount of time elapsed when the particle strikes one of the plates, At, numerically: At = 0.18 Grade Summary S Deductions Potential 98% sin( cos tan( . 7 8 9 HOME Submissions cotan( asin( acoso F TA 4 5 Attempts remaining: 9 atan( acotan( sinh( 2 3 (2% per attempt detailed view cosh() tanh() cotanh() + 0 END 1 2% ODegrees O Radians VO BACKSPACE DEL CLEAR Submit Hint Feedback I give up!

When setting up the y-displacement, remember that the particle started halfway between the two plates, so it didn't travel the whole distance between the plates. 8% Part (1) Set up the kinematics x-givens table for computing the x-component of the final displacement. Which of the five kinematics givens are knowns at this point? Select all that apply. Vix ax; At V Correct!

Consider a drop of oil of charge q = 2.41E-17 C and mass m = 1.22E-12 kg passing through the region between a pair of infinitely long horizontal plates separated by a distance d= 3.11 m with a uniform electric field E = (0.0,222000)N/C. The particle begins A A S moving horizontally with an initial velocity of V vo = (44, 0.0)m's from a position halfway - (vertically) between the two plates. Gravity is in the negative y direction. Compute how far horizontally, in meters, the particle will travel before striking one of the plates, using the standard plan for analyzing a forces problem and a kinematics problem, as outlined in the steps below: +y Vo +XStep by Step Solution
