Determine the height from the ground where the two balls pass each other.

A diver springs upward from a board that is 2.90 m above the water. At the instant she contacts the water her speed is 12.2 m/s and her body makes an angle of 64.6° with respect to the horizontal surface of the water. Determine her initial velocity, both (a) magnitude and (b) direction. 00

Q2. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mA = 23 Mg and mg = 14 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VA,1 4.3 m/s and v³,1 = 2.9 m/s. Determine the velocity of A after collision if the cars collide and rebound, such that B moves to the right with a speed of 1.8 m/s. Right is considered the positive direction and negative sign must be included if A moves to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Your Answer: VA,1 Answer units B VB.1 =
