Q1. What mass (in grams) of steam at 100 C must be mixed with 175 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 50.0 C?
Q2. On a dry road, a car with good tires may be able to brake with a constant deceleration of 4.28 m/s2. (a) How long does such a car, at first travelling at 26.4 m/s, take to stop? (b) How far does it travel in this time?
