This is a symbolic version of Problem 29. A river has a steady speed of vs. A student swims upstream a distance d and back to the starting point. (a) If the student can swim at a speed of v in still water, how much time tup does it take the student to swim upstream a distance d? Express the answer in terms of d, v, and vs. (b) Using the same variables, how much time tdown does it take to swim back downstream to the starting point? (c) Sum the answers found in parts (a) and (b) and show that the time ta required for the whole trip can be written as ta=2d/v1-vs2/v2 (d) How much time tb does the trip take in still water? (e) Which is larger, ta or tb? Is it always larger?

A fireworks shell is accelerated from rest to a velocity of 65.0 m/s over a distance of 0.250 m. (a) How long did the acceleration last? (b) Calculate the acceleration.
You are watching a friend practice archery when he misses the target completely, and the arrow sticks into the ground. Discouraged, your friend asks whether you can help by estimating the speed with which the arrow left the bow. Remembering your physics class, you realize that you can do so by measuring its height above the ground when it was launched, if you assume the arrow was launched horizontally and that the ground is level. For your analysis, you let h represent the arrows height above the ground when it was launched, v0 represent the launch speed, and represent the angle the arrow makes with the horizontal when it is stuck into the ground. Find an expression for v0 in terms of h and .
The graph in Figure 1.38 shows the distance versus time for an elevator as it moves up and down in a building. Compute the elevator's velocity at the times marked a, b, and c.
An object that is thrown straight up falls back to Earth. This is one-dimensional motion. (a) When is its velocity zero? (b) Does its velocity change direction? (c) Does the acceleration have the same sign on the way up as on the way down?
