A 0.75-kg mass moving with a speed of 5.0 m/s encounters a 0.25-kg mass moving in the opposite direction with speed 5.0 m/s. Assume the objects collide in an elastic collision where no energy is lost.
If the charge on the plates is adjusted until the bead is stationary (doesn't fall due to gravity), what is the resulting electrostatic potential difference between the plates?
During this time the drive slows down due to friction which provides a constant deceleration, and the drive makes exactly 2200 revolutions (but is not at rest). aA) What is the angular speed (in rad

I) Assume the two objects collide and stick together. What is the velocity of the combined mass after the collision?
The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. The ball is in contact with the wall for t = 0.079 s. 1
What should be the refractive power (in diopters) of her glasses (worn2.0 cmfrom the eyes), so she can read the newspaper at a distance of 24 cmfrom the eyes?
A rod length 2.0m is uniformly charged and has a total charge of 5.0 nC. What is the electric potential at a point which lies along the axis of the rod and is 3.0 m from the center of the rod?
A camera with a telephoto lens (f = 220.0mm) is to be focused on an object located first at a distance of 3.5 m and then at 45.0m. Over what distance must the lens be movable?
