A particle travels horizontally between 2 parallel walls separated by 18.4 m. It moves toward the opposing wall at a constant rate of 5.5 m/s. Also it has an acceleration in the direction parallel to the walls of 1.8 m/s^2.What will its speed be when it hits the opposing wall? answer in m/s.

At what angle with the wall will the particle strike? Answer in units of degrees.

    Horizontally:
    Vavg = x/t so t x/Vavg
    t = 18.4 m/5.5m/s = 3.345 sec

    Vertically: (parallel to the wall)
    Assuming initial velocity in this direction is zero

    Vfinal = Vinitial + at so:
    Vfinal = 0 + (1.8 m/s^2)(3.345 sec) = 6.0 m/s

    Using pythagorean theorem to find the final velocity and tangent to find the angle:

    Square root (5.5 ^2 + 6^2) = 8.14 m/s
    tan x = 6/5.5 = 47.5 degree with respect to the horizontal so 42.5 degrees with respect to the wall.
