A car travels along a straight line at a constant speed of 45.5 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 29.5 mi/h.(a) What is the constant speed with which the car moved during the second distance […]

(Absolute zero is -457.0 F.) A football is filled to a gauge pressure of 15.8 psi when its temperature is 80.0°F. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.) After the ball has cooled to 58.8°F. (a) Assuming that the volume of the football does not change, and that air behaves […]
A proton and an electron are held in place on the x-axis. The proton is at , while the electron is at . They are then released from rest simultaneously and allowed to interact via the electric force. Which particle reaches the origin first? They reach the origin at the same time. The proton. The […]
