3. As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The below figure gives their velocities v as functions of time t as the conductors slow the trains. The figure's vertical scaling is set by vş = 40.0 m/s. The slowing processes begin when the trains are 200 m apart. What is their separation when both trains have stopped? 40 m v (m/s) IN I 4 6t(s)

A car traveling at 20m/s is attempting to drive up an icy hill. When it getsonto the hill, it is able to go 10 meters before it hits some ice and begins sliding. Assume the hillis a 10 degree incline. A. How far up the hill does the car travel before it starts to slide back down? Make sure toinclude the initial 10 meters in your final distance. B. If the car then slides all the way back to the bottom of the hill, what is its speed when itgets to the bottom? Assume it doesn’t gain traction back, so it is sliding with no frictionthe whole way down.

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?

Unreasonable results A dolphin in an aquatic show jumps straight up out of the water at a velocity of 15.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known, and identify its value. Then, identify the unknown and discuss how you chose the appropriate equation to solve for ft. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long a time is the dolphin in the air? Neglect any effects resulting from his size or orientation.
