A 0.125-kg hockey puck is sliding North across a frictionless ice surface at a constant speed of 39 m/s when a hockey stick exerts a force of 32 N [S25oE] on the puck for 0.15 s. Find the final velocity of the hockey puck.

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?
