1. A Carnot heat engine takes 2000J of heat from the high temperature reservoir at 227 degrees Celsius, does some work and discards heat into the low temperature reservoir at 77 degrees Celsius. What is the Carnot efficiency? How much work does the engine do and how much heat is discarded?
2. Suppose 1.00kg of water at 100 degrees Celsius is mixed with 1.00kg of water at 0 degrees Celsius. What is the total charge in entropy of the mixture?
A 10 N force acts on 5 kg object for 2.0s. What is the impulse of the force on the object, What is the change in momentum of the object
During a fun run a girl runs for 12 s moving 2.7 m/s. She then accelerates at 0.5 m/s^2 over the next 25 m. she then runs at her new speed for 10s. What distance did she cover during the entire period?

If 54 J of work are needed to stretch a spring from 15 cm to 21 cm and 90 J are needed to stretch it from 21 cm to 27 cm, what is the natural length of the spring
An electron accelerated from rest through a voltage of 350V enters a region of constant magnetic field. If the electron follows a circular path with a radius of 28cm, what is the magnitude of magnetic field.
A 5 kg block, measuring 10 cm per side, is held 50% submerged in water by a helium balloon. what is the diameter of the balloon
If the balloon is 24.9 cm in diameter when child loses it, what is its diameter at an altitude of 1510 m? Assume that the balloon is very flexible and so surface tension can be neglected.
