Explanation Given Info: Average induced emf ε is 12.0 mV , the rate of change of current Δ I is 3.5 A − 2 .0 A the change in time Δ T is 0.50 s . Formula to calculate the magnitude of the average induced emf in the coil is, | ε | = L | Δ I Δ t | | ε | is the magnitude of the average induced emf in the coil, L is the self inductance of the coil, Δ I is the rate of change of current, Δ t is the change in time, Rearrange in terms of L L = | ε | | Δ t Δ I | Formula to rate of change in current is, | Δ I | = | I f − I i | I f is the final amount of current, I i is the initial amount of current, Use | I f − I i | for Δ I in L = | ε | | Δ t Δ I |

2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, 0, y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0.,y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).
