An airplane refuels in Bakersfield and continues on to Fresno. It travels an average speed of 610 km/h. IF the trip takes 2.75 hours, what is the flight distance between Bakersfield and Fresno?

A 4.25 g bullet traveling horizontally with a velocity of magnitude 375 m/s is fired into a wooden block with mass 1.10 kg, initially at rest on a level frictionless surface.

Oxygen gas having a volume of 1010 cm3 at 20.7°C and 1.04 x 105 Pa expands until its volume is 1570 cm3 and its pressure is 1.07 x 105 Pa. Find (a) the number of moles of oxygen present and (b) the final temperature of the sample.

2. Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constant current. (Use a numerical value for the constant.)

Three students derive the following equations in which x refers to distance traveled, v the speed, a the acceleration (m/s^2), and t the time, and the subscript (0) means a quantity at time t=0: a) x=vt^2 + 2at, b) x=v0t+1/2at^2, and c) x=v0t+2at^2.
