Towns A and B in Figure P4.64 are 80.0 km apart. A couple arranges to drive from town A and meet a couple driving from town B at the lake, L. The two couples leave simultaneously and drive for 2.50 h in the directions shown. Car 1 has a speed of 90.0 km/h. If the cars arrive simultaneously at the lake, what is the speed of car 2?
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?

A bottle rocket is shot straight up in the air with a speed 30 m/s. if the air resistance is ignores, the bottle would go up to a height of approximately 46 m. however the rocket goes up to only 35 m before returning to the ground. What happened? Explain, giving only a qualitative response.
Hi, I have one more follow-up question regarding a similar problem where I need to find the height: In a rollercoaster ride a passenger car at the top of the first hill is travelling at 3.5 m/s. The carthen descends on rails to the bottom of the slope and then goes up the second hill where the speed is 10 m/s. Find the difference in height between the first and second hill. (Result 4.47m) Attached is the formula I tried to use, however, I get a different result so I am definitely doing something wrong. Online I didn't find a similar problem so I am asking here as a last chance. Can you help?
