Q1. Two boats start together and race across a 64-km-wide lake and back. Boat A goes across at 64 km/h and returns at 64 km/h. Boat B goes across at 32 km/h, and its crew, realizing how far behind it is getting, returns at 96 km/h. Turnaround times are negligible, and boat that completes the round-trip first wins.

Q2. A ball is thrown upward from the ground with an initial speed of 25m/s; at same instant, a ball is dropped from rest from a building 15m high. After how long will the balls be at the same height?
