A car of mass 1800 kg collides with a truck of mass 5200 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was < 44, 0, 0 > m/s, and the truck's velocity just before the collision was < -21, 0, 20 > m/s. Use the concept of the center-of-momentum reference frame.

An electron moves with a constant horizontal velocity of 3.0 ร 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
