Design an operational amplifier capable of providing a voltage gain of at least 500 v/v to a load as small as r 1k. the circuit will include a differential amplifier, and additional amplifier stages. the input voltage is considered to be differential, while the output voltage should be measured with respect to the ground. the dc voltage at the output should be offset to 0v. you are only allowed to use resistors, bjts, and mosfets in your design. do not use capacitors or operational amplifiers since 500 v/v is not a small gain, the amplifier may not work properly for a large peak-to-peak input. determine what the maximum peak-to-peak input should be, based on your design.

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
