You have two people, one of whom is standing at the bottom of a building and another who is standing at the top. The person at the bottom of the building throws a ball vertically upward at 40.0 m/s at the same instant the person at the top releases an identical ball from rest. If the vertical distance between release points is 1.00 x 102 m how far from the top of the building do the two balls meet? Ignore...

Need help with part B (the sketching!) thanks
Problem 3: A thin flat plate of length L-120 mm, thickness t=4 mm, width W=30 mm, and thermal conductivity k=20 W/m-K is thermally joined to heat sinks at different temperatures, where T(x = 0) = To-100 C and T(x = L) = T,-35°C. The top surface of the plate is subjected to uniform heat flux q"-20 kW/m2, and the bottom surface of the plate is subjected to uniform convection with a convection...
