The voltage V(1) (in V) and the current i(t)
(in Amp) t seconds after closing the switch in
the circuit shown are given by:
R
Vdt) = V(1– e/)
i(t) = e,
where t, = RC is the time constant. Consider the case where V = 24 V,
R = 3800 2 and C = 4000 x 10-6 F. Determine the voltage and the current
during the first 20 s after the switch is closed. Create a vector with values of
times from 0 to 20 s with spacing of 2 s, and use it for calculating V(1) and
i(t). Display the results in a three-column table where the values of time.
voltage and current are displayed in the first, second, and third columns,
respectively.
(To display values in a Table, just create
matrix and have its output displayed)

- standard science experiment is to drop a ball and see how high it bounces. Once the “bounciness” of the ball has been determined, the ratio gives a bounciness index. For example, if a ball dropped from a height of 10 feet bounces 6 feet high, the index is 0.6, and the total distance traveled by the ball is 16 feet after one bounce. If the ball were to continue bouncing, the distance after two bounces would be 10 ft + 6 ft +6 ft + 3.6 ft = 25.6 ft. Note that the distance traveled for each successive bounce is the distance to the floor plus 0.6 of that distance as the ball comes back up. Write a program that lets the user enter the initial height from which the ball is dropped, the bounciness index, and the number of times the ball is allowed to continue bouncing. Output should be the total distance traveled by the ball.arrow_forwardThe table below describes the average voltage generated, A, in volts by an energy harvester for three days at three different times for each day.
