A (0.160-mathrm{kg}) hockey puck modified to hold (+50 mu mathrm{C}) of charge is placed at one end
Question:
A \(0.160-\mathrm{kg}\) hockey puck modified to hold \(+50 \mu \mathrm{C}\) of charge is placed at one end of an ice hockey rink that is \(61 \mathrm{~m}\) long. At the other end of the rink is a device capable of generating a charge of \(-0.10 \mathrm{C}\), but only for a short time interval. The coefficient of kinetic friction between ice and puck is \(\mu_{k}=0.015\). The puck is given a tiny nudge (just enough to get it moving but at a speed of nearly 0 , which means you can ignore static friction), and then the charge generator is turned on for \(100 \mathrm{~ms}\).
(a) Is the puck able to reach the generator?
(b) If so, what is the puck's speed when it arrives at the generator? (For both parts, assume the 100 -ms time interval is short cnough to allow you to assume that the distance between the puck and the charge generator is constant.)
