A 345g hockey puck rests on a flat smooth table. A horizontal force of 125 N acts on it for 2 seconds. The puck slides across the table at the end of that time and then falls off the table. The table's top surface is 85 cm above the deck. Find the a) acceleration of the puck, b) the speed of the puck after the 2 seconds and c) the horizontal distance from the table edge to where the puck impacts the deck.
