A muscle is pulling a 3kg steel block upwards as shown in the figure below. This is an isotonic pull. There are two forces at play here: the mass' weight and the muscle's pulling tension (the weight's drag is considered as negligible). Use the work-energy theorem to calculate the amount of tension generated by the muscle. a) 22.27N b) 26.60N c) 29.27N d) 29.43N Tendon Muscle contracts (isotonic contraction) 3 kg Vanish = Om/s Tendon h= 0.87 m Vatart = 0.3 m/s 3 kg motion
