A 815-kg car stopped at an intersection is rear-ended by a 1740-kg truck moving with a speed of 13.0 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of both vehicles after the collision.
___ (car)
___ (truck)

The loaded cab of an elevator has a mass of 3.0 x10^3 kg and moves 157m up the shaft in 23s at constant speed. At what average rate does force from the cable do work on the cab.
When the walkway exerts a load force of 9900 N on one of the support points, through what distance does the point move down?
A 0.300-kg mass, attached to the end of a 0.750-m string, is whirled around in a smooth level table. If the highest tension that the string can withstand is 250 N, after that what highest linear speed can the mass have if the string is not to brea..
An electric dipole has opposite charges of 5.0x10^-15 C separated by a distance of .40mm. Determine the magnitude of the torque exerted on the dipole by the electric field
In lectures and in tutorials, we discussed the confinement of an electron (or other particle) to a box of infinite depth, running from x = 0 to x = a. If we, instead, define this 1-D region of confinement as running from -(a/2) to (a/2)
The displacement of an object moving under uniform acceleration is some function of time and the acceleration. Suppose we write this displacement as s=ka^mt^n, where k is the dimensional constant. Show by dimensional analysis that this expression ..
