A particle travels horizontally between two

parallel walls separated by 18.4 m. It moves
toward the opposing wall at a constant rate
of 5.9 m/s. Also, it has an acceleration in the
direction parallel to the walls of 2.2 m/s^2. a) What will be its speed when it hits the opposing wall? Answer in units of m/s. b) At what angle with the wall will the particle strike? Answer in units of °.

1 answer

time to hit = 18.4/5.9 = 3.12s
(a) = √(18.4^2 + (2.2*3.12)^2) =
(b) arctan(18.4/6,86)
