Kinematics

A ball is dropped from a height of 39.0 m. The wind is blow­ing horizontally and imparts a constant acceleration of 1.20 m/s2 to the ball. 

(a) Show that the path of the ball is a straight line and find the values of R and θ in the figure below. 

(b) How long does it take for the ball to reach the ground? 

(c) With what speed does the ball hit the ground?
