Now, suppose that zak's younger cousin, greta, sees him sliding and takes off her shoes so that she can slide as well (assume her socks have the same coefficient of kinetic friction as zak's). 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 d2 does she slide after zak's push ends?

Work is a from of energy, thus, work is also conserved. Hence, the work exerted by the Zak is transferred to her as she covers the distance. The formula for work is force times distance. The solution is as follows:

(125 N)(1 m) = (20 kg)(1000 g/1 kg)(9.81 m/s²)(d)
Solving for d,
d = 6.37×10⁻⁴ m
