1. Velocity = 344m/s
Distance = 1.5m
Total distance = 1.5 x 2 = 3m
Velocity = distance/time

1. The maximum distance possible number of individual measurements per second
if the distance turns out to be 1.50m and the velocity of the ultrasound waves is
equal to 344 m/s is 114.7 pulses per second.
Velocity: 344m/s
Distance: 1.

Conceptual Questions:
1. Yes, you would be able to tell if the elevator was moving upward or downward
based on looking at the scale. This is due to the weight on the scale reflecting the
acceleration the elevator initially has when it goes from resting to
