P. 4519. Recently, one of the greatest sensation was Felix Baumgartner's stratosphere jump. The Austrian sky-diver jumped out of the capsule, lifted by a Helium balloon, at a height of 39045 metres and opened his parachute after falling for 4 minutes and 17 seconds. According to the video which can be seen on the world wide web, in the first part of his motion his speed changed as it is shown in the table below:
a) Plot the speed-time and the acceleration-time graphs of the motion in the first 64 seconds.
b) His greatest registered speed was 1300 km/h, which is 1.2 times the actual speed of sound. Estimate when would he reach this record, if only the effect of gravity is counted.
