A group is playing kickball on a flat field. A 750g=0.750kg ball is kicked and has an initial velocity of <8.0, 10.0, 0> m/s after leaving the kicker's foot. What is the maximum height that the ball reaches (ignore air resistance)? Note that the y-direction is up-and-down. A. 20.4 m
B. 5.10 m
C. 15.3 m
D. 0.00 m
E. 10.2 m
F. 40.8 m

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
