4. which muscle fibers are best suited for sprinting? yellow fibers motor-neuron cells red fibers white fibers its not d 5. which muscle fibers are best suited for sprinting? yellow fibers motor-neuron cells red fibers its not a white fibers

everyone keeps saying 4 is a, yellow fibers...ITS WRONG

the answer to 4 is Motor-neuron cells, i just did the assignment.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
