Problem 2.55

A sprinter explodes out of the starting block with an acceleration of 2.3 m/s2 , which she sustains for 1.2 s. Then, her acceleration drops to zero for the rest of the race. What is her velocity (a) at t 1.2 s and (b) at the end of the race? 19

Step 1 of 3

Block 3 Lecture 1 - Graded Potentials & Action Potentials 1. Identify the functional regions of a neuron and describe how they facilitate neuronal communication Receptive region​ - dendrites and cell body - binding of neurotransmitters, generating graded potential Impulsive-generating Region​ - axon hillock - summation of graded potentials, inition of action potential Conducting Region​ - Axon propagation of action potentials Secretory Regions​ - Axon terminals - release neurotransmitters 2. Identify where specific ion channels are located on a neurons Entire membrane ​- maintains resting membrane potential K+ leak channels (lots) Na+leak channels Na+/K+ pumps Receptive Segment​ - generates graded potentials - chemical-
