The drawing shows a 18.58 kg crate that is
initially at rest. note that the view is one looking
down on the top of the crate. two forces, f 1
and f 2, are applied to the crate, and it begins
to move. the coefficient of kinetic friction
between the crate and the floor is 0.54.
determine the magnitude of the acceleration of
the crate (m/s2).

f1: 88n
f2: 54n
the angel between f1, f2 : 55

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.
