Question 5 (4 pts)
The coefficient of kinetic friction between the surface and the larger block is 0.25 , and the coefficient of kinetic friction between the surface and the smaller block is 0.40 . If \( F=22 \mathrm{~N} \) and \( M=1.0 \mathrm{~kg} \) in the figure, what is \( a \), the magnitude of the acceleration of either block? Express your answer in terms of \( g \), the magnitude of the gravitational acceleration at the surface of the earth - that is, obtain the dimensionless ratio \( a / g \).
Hint: Start by drawing a force diagram for each mass.
Question 6 ( 4 pts )
A block of mass \( m=10 . \mathrm{kg} \) is released from rest from a height \( h \) except for a \( d=6.0 \mathrm{~m} \) long part of the horizontal surface where \( \mu=0.20 \). The block travels down the track, hits a spring of forc compresses the spring an amount \( \Delta x=0.40 \mathrm{~m} \) from its equilibr momentarily.
