V = IR
I = current
R = resistance
Voltage = 100 * (3.44x 10^-4) = do the calculation
Hope this helps
<h2>a) Average velocity in first 4 seconds is 64 ft/s upward</h2><h2>b) Average velocity in second 4 seconds is 63.5 ft/s downward</h2>
Explanation:
a) Given S(t) = 76 + 128t − 16t²
s(0) = 76 + 128 x 0 − 16 x 0² = 76 ft
s(4) = 76 + 128 x 4 − 16 x 4² = 332 ft
Displacement in 4 seconds = 332 - 76 = 256 ft
Time = 4 - 0 = 4 s
![\texttt{Velocity = }\frac{256}{4}=64ft/s](https://tex.z-dn.net/?f=%5Ctexttt%7BVelocity%20%3D%20%7D%5Cfrac%7B256%7D%7B4%7D%3D64ft%2Fs)
Average velocity in first 4 seconds is 64 ft/s upward
a) Given S(t) = 76 + 128t − 16t²
s(4) = 76 + 128 x 4 − 16 x 4² = 332 ft
s(8) = 76 + 128 x 8 − 16 x 8² = 78 ft
Displacement in 4 seconds = 78 - 332 = -254 ft
Time = 4 - 0 = 4 s
![\texttt{Velocity = }\frac{-254}{4}=-63.5ft/s](https://tex.z-dn.net/?f=%5Ctexttt%7BVelocity%20%3D%20%7D%5Cfrac%7B-254%7D%7B4%7D%3D-63.5ft%2Fs)
Average velocity in second 4 seconds is 63.5 ft/s downward
