Answer:
Explanation:
Momentum change for either skater is mΔv = 75.0(5.0) = 375 kg•m/s
As a change in momentum is equal to an impulse
375 = FΔt
F = 375/0.100 = 3750 N
As 3750 N < 4500 N no bones are broken.
Answer:
l = 3.21 mm
Explanation:
The efficiency of a fiber-reinforced is the following:

<u>Where: </u>
η: is the efficiency
l: is the fiber length
x: is the length of the fiber at each end that doesn't contribute to the load transfer
So the length required for a 0.62 efficiency of reinforcement is:
