Describe the effects of the unbalanced forces on each of these objects.
- A bicycle is moving in a straight line. There is an unbalanced force
opposite to the direction the bicycle is moving.
- A car is moving in a straight line. There is an unbalanced force in
the same direction as the car is moving.
- A ball is moving in a straight line. There is an unbalanced force
sideways to the direction the ball is moving.

An electron moves with a constant horizontal velocity of 3.0 × 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.)
