Now that we have a feel for the state of the circuit in its steady state, let us obtain the expression for the current in the circuit as a function of time. note that we can use the loop rule (going around counterclockwise): e−vr−vl=0. note as well that vr=ir and vl=ldidt. using these equations, we can get, after some rearranging of the variables and making the subsitution x=er−i, dxx=−rldt. integrating both sides of this equation yields x=x0e−rt/l. use this last expression to obtain an expression for i(t). remember that x=er−i and that i0=i(0)=0. express your answer in terms of e, r, and l. you may or may not need all these variables. use the notation exp(x) for ex.

Mark saxby is set to kick the field goal to win the state championship for olathe east. he is 47m away from the goalposts, and he kicks the ball at a speed of 25.0m/s at an angle of 30.0°. if the cross bar on the goalposts is 3.00m above the ground, will the ball make it over the cross bar? and if it does make it, by how much will it clear?
