5
Step-by-step explanation:
Answer: Sample size would be 296.
Step-by-step explanation:
Since we have given that
Standard deviation = 4.8 hours
Margin of error = 0.65 hours
At 98% level of confidence, z = 2.33
So, It becomes,

Hence, sample size would be 296.
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
First piece is 5.2 cm...and second piece is 1.5 times as long
1.5(5.2) = 7.8 cm <== second piece
