A particle travels horizontally between two
parallel walls separated by 18.4 m. It moves
toward the opposing wall at a constant rate
of 6.7 m/s. Also, it has an acceleration in the
direction parallel to the walls of 1.7 m/s2 .
What will be its speed when it hits the
Answer in units of m/s.
You need to know the horizontal velocity component at time zero. You also need to know if it starts out between the walls, or somewhere else.
