Activity In this activity you'll use the Data tool in Tracker. If it isn't already open, open the Tracker ball drop 1 C experiment. Part A Predict the velocity vy when y = -3.5 meters. Use the average acceleration you calculated in Activity 1. Use the formula v2 = V02 + 2ay, where v = final velocity, vp = initial velocity, a = average acceleration, and y = y displacement. (Note that vis the final velocity in the y direction: v.) V2X 15nY !! 11 lil = 9

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

It would be c. risk.
