A Mass M Is Released from a Height 60 Cm μ\mu

Question 10

Multiple Choice

A mass m is released from a height 60 cm from the right-hand side of the track shown in the diagram at right.There is only friction acting on the mass on the horizontal portion 35 cm either side of the midpoint O,with a kinetic coefficient of friction of μ\mu k = 0.5.Determine what is the velocity of the block the first time it passes through the midpoint,and on which side of the midpoint does it stop?
