The acceleration of gravity at the surface of Mars is 3.7 m/s². If a stone is thrown upward in Mars reaches a height of .01 km. Find its a) initial speed; b) the total time of flight; and c) its location after 1.5 sec.

A ball reaches the ground in 5 seconds. a) From what height in meters was it dropped? b) What would be its final velocity? c) How far has it fallen in the last second of its travel?

A stone is dropped from a height of 25 meters. a) How long will it take for the stone to hit the ground? b) What velocity does it have when it hits the ground?

The 8-bit registers R1, R2, R3, and R4 initially have the following values:

R1 - 1111 0010, R2- 1 1 1 1 1 1 1 1 , R3- 1011 1001 , R4 1 1 101010

Determine the 8-bit values in each register after the execution of the following sequence of 

microoperations.

R1 <-R1 + R2 

R3<- R3 ^ R4, R2 <- R2 + 1 

R1 <- R1 – R3

Customer arrives at an internet center at the rate of one every 15+-5 minutes. 80% of the customers check simply their email inbox, while the remaining 20% download and upload files. An email customer spends 15+-2 minutes in the center and the download customer spends 15+-5 minutes. Simulate the service completion of 500 customers. Of this 500 customer, determine the no. of email and download customer and with the input percentage.

a common bus system which is capable of transferring 2 bits at time with number of registers are 4 each register is of 2 bit? draw circuit diagram for this and also define how many multiplexers are required and what will be the size of multiplexer with truth table also explain how to gather data from this back into regsiter

design a circuit that would be able to shift bits but also store them for a duration of time. explain what are the technicalities of such a circuit
