Estimate the minimum and maximum compressive strengths of bone in [mpa]. assume that: (1) the compressive strength of hydroxyapatite is 500 mpa and that of collagen is 1 mpa and (2) the volume fraction of hydroxyapatite in bone is 20% and the rest is collagen

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
