Suppose that Zak's younger cousin, Greta, sees him sliding across the hall and takes off her shoes so that she can slide as well (assume her socks have the coefficient of kinetic friction of 0.250). Instead of getting a running start, she asks Zak to give her a push. So, Zak pushes her with a force of 125 N over a distance of 1.00 m. If her mass is 20.0 kg, what distance d does she slide after Zak's push ends? Remember that the frictional force acts on Greta during Zak's push and while she is sliding after the push.
