Please Show work.

Two cars are approaching each other on the highway. Car A is driving west at 48 mph. Car B is driving east at 65 mph with an acceleration of -1.0 m/s2. At t1 = 0 s, a person in car A throws a ball vertically upward with respect to their own reference frame, with an initial velocity of 8 m/s. What is the speed of the ball at tf = 9 s, relative to an observer sitting in car B? Use the value of g = 9.8 m/sA2 for Earth's acceleration constant. At t = 9 s, the ball is moving at a speed m/s relative to an observer in car B.
