The baseball player A hits the baseball at vA = 40 ft/s and ?A = 60? form the horizontal. As soon as the ball is hit player B begins to run forward. Determine the constant speed vB at which B must run and the distance d in order to make the catch at the same elevation at which the ball was hit. We will solve this problem using relative motion analysis. Assume the xy coordinate system is fixed to player B, i.e., it is a coordinate system having translating axes.
1.Determine the total traveling time of the ball by analyzing its vertical motion.
2. Use vB for the unknown speed at which B must run. What is the relative velocity in the x direction (vb/B)x of the ball relative to player B, i.e., the velocity of the ball observed in the xy coordinate system?
3. What is the relative displacement sb/B of the ball relative to player B, i.e., the displacement of the ball observed in the xy coordinate system, when the ball is caught? Find vB using (vb/B)x and sb/B.
4. Find d.

...Select the correct answer from each drop-down menu.
- A function is a relation where each input value is assigned to exactly, less than, or at least one output value.
- The domain, rate of change, interval, or range of a function is the set of all input values, or x-values, for which the function is defined.
- The interval, domain, rate of change, or range of a function is the set of all output values, or y-values, for which the function is defined.
- To write the equation y = ax + b in function notation, x, b, f(x), or a substitute for y.
