Solve the system of equations given in the previous hint, and find an expression for x1x1x_1 in terms of the following variables: x0Ax0Ax_0A, the initial position of puck A; x0Bx0Bx_0B, the initial position of puck B; v0Av0Av_0A, the initial speed of puck A; and v0Bv0Bv_0B, the initial speed of puck B. Note that since we are now using the initial speeds of the pucks, the two equations become:

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m

Abeam of electrons with of wavelength of 7.5 x 10-6 m is incident on a pair of narrow rectangular slits separated by 0.75 mm. the resulting interference pattern is projected onto a screen 10.0 m from the slits. what is the separation of the interference maxima in the resulting interference pattern?

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?
