A father racing his son has 1/4 the kinetic energy of the son, who has 1/3 the mass of the father. The father speeds up by 1.6 m/s and then has the same kinetic energy as the son. What are the original speeds of (a) the father and (b) the son?

A single force acts on a 4.8 kg particle-like object in such a way that the position of the object as a function of time is given by x = 1.1t - 1.6t2 + 4.1t3, with x in meters and t in seconds. Find the work done on the object by the force from t = 0 to t = 1.5 s.

A 50 gram sample of delicious pork rinds is placed in an open, constant pressure calorimeter that contains 3000 grams of water. The temperature of the water increases by 47◦C when the pork rinds are combusted. The heat capacity of water is 4.184 J/g ◦C. Assume the heat lost to the calorimeter itself or to the air is negligible. Which of the following is correct for the SYSTEM?
