Erfan pushes a 5kg crate of stage props starting from rest along the smooth and slippery horizontal floor of a theater stage. The crate moves with a constant acceleration for 10 seconds as Erfan pushes with a force of 0.22 N to reach the edge of the stage. Then the crate runs off the edge of the stage and lands in the orchestra pit below. The floor of the orchestra pit is 3 meters below the edge of the stage. Assume friction is negligible. How far away from the stage edge does the crate land?

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =
