4. consider muscle fibers that are 8 cm long and that develop a maximum of 20 n/cm2 force. consider a muscle that has a volume of 20 cm3 with the fibers aligned with the direction of the tendon (θ=0).
a.) what is the maximum force developed by this muscle? (5 points)
b.) if partial recruitment results in activation of 10% of the muscle fibers (assuming they are all of equal size), how much force could the muscle generate? (5 points)
c.) if the muscle fibers contract 15% of their length in 50 ms under no load, what is the maximum muscle velocity? (5 points)
d.) suppose the muscle fibers are oriented at 15° relative to the tendon axis, with the same volume of muscle. what is the maximum force delivered to the tendon? what is the maximum velocity? (5 points)

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
