A train is traveling at 60kph along a straight track. If a ball is thrown forward at an angle of 30 degrees above the horizontal in the direction of the train with a velocity of 20m/s relative to the train, 5m above the ground, determine its speed when it strikes the ground. Answer in m/s Hint: Use resultant of VBx and VBy
