A rocket is moving in a gravity free space with a constant acceleration of 2ms-² along +x direction (see figure). The length of a chamber inside the rocket is 4m. A ball is thrown from the left end of the chamber in +x direction with a speed of 0.3ms-1 relative to the rocket. At the same time, another ball is thrown in -x direction with a speed of 0.2ms-1 from its right end relative to the rocket. The time in seconds when the two balls hit each other is:

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
