Problem #2
a nerve conduction velocity test (ncv) is an electrical test that is used to evaluate the function of nerves.
a ncv on a patient's sciatic nerve (length of 0.90 m) reveals a conduction velocity of 30 m/s. how long
did it take the impulse to travel along the nerve?
problem #3
two boats start together and race across a 64 km wide lake and back. boat a goes across at 64 km/h and
returns at 64 km/h. boat b goes across at 32 km/h and its crew, realizing how far behind it is getting,
returns at 96 km/h. turnaround times are negligible, and the boat that completes the roundtrip first wins.
a) which boat wins? (or is it a
b) this boat won by how much? ( 64 kilometers)
c) what is the average velocity (in km/hr) of the winning boat?
