A hovercraft is sitting on the shore of a river that is 1 mile wide. The hovercraft is supposed to reach a camp that is located 3 miles downstream on the other side of the river. You need to decide the fastest route in each of these two situations: a) The opposite shore is smooth, so that the crafts speed on water will be 2/3 of that on shore. b) The opposite shore is rather rough, so that the crafts speed on land is 2/3 of that on the water.

A 547g squirrel with a frontal surface area of 0.0145m2 falls to the ground from a 5.3m tree. Assume the density of air is 1.21kg/m3. Neglecting the drag force, what is the velocity, in meters per second, of a 56kg person after falling, from rest, by that same distance?
When salmon head upstream to spawn, they may encounter a waterfall. If the water is not moving too fast, the salmon can swim right up through the falling water. Otherwise, the salmon jump out of the water to get to a place in the waterfall where the water is not falling so fast. When humans build dams that interrupt the usual route followed by the salmon, artificial fish ladders must be built. The consist of a series of small waterfalls with still pools of water in between them. Suppose the salmon can swim at 5.40 m/s with espect to the water. What is the maximum height of the waterfall up which the salmon can swim without having to jump? If a waterfall is 1.90 m high, how high must the salmon jump to get to water through which it can swim? Assume that they jump straight up. What initial speed must a salmon have to jump the height to get to water through which it can swim? For a 1.00-m high waterfall, how fast will the salmon be swimming with respect to the ground when it starts…

A railroad car which has a mass 9216 kg is constrained to move along a horizontal track under the action of a wind blowing in the direction of the track. The frictional resistance to the car motion is 1/200 of its weight. The force exerted by wind is P=kSu2, where S is the area of the backside of the railroad car, equals to 6 m2, and u is the velocity of the wind relative to car, k=0.12. The absolute velocity of the wind is w=12 m/s. The initial velocity of the railroad car is 0. Determine:a) the maximum velocity vmax of the railroad car;b) the time T taken to reach this velocity;c) the distance x, travelled by the railroad car before reaching a velocity of 3 m/s
Like friction, drag force opposes the motion of a particle in a fluid; however, drag force depends on the particle's velocity. Find the expression for the particle's velocity v(x) as a function of position at any point x in a fluid whose drag force is expressed as Fdrag = kmv where k is a constant, m is the mass of the particle and v is its velocity. Assume that the particle is constrained to move in the x-axis only with an initial velocity v0. Solution: The net force along the x-axis is: ΣF = -F = m then: -mv = m Since acceleration is the first time derivative of velocity a = dv/dt, -mv = m We can eliminate time dt by expressing, the velocity on the left side of the equation as v = dx/dt. Manipulating the variables and simplifying, we arrive at the following expression / = -k "Isolating" the infinitesimal velocity dx and integrating with respect to dx, we arrive at the following: = v0 - which shows that velocity decreases in a linear manner.

A light plane flies north from Hamburg to Kiel (100 km) with an air speed of of 340 km/h through air. Compute the flight time without wind, with tail winds 80 km/h, and with winds from NNE of 80 km/h.
By comparing the surface area of a sphere with its volume and assuming that air resistance is proportional to the square of velocity, it is possible to make a heuristic argument to support the following premise: For similarly shaped objects, terminal velocity varies in proportion to the square root of the length. Expressed in a formula, this is T = kL0.5, where L is length, T is terminal velocity, and k is a constant that depends on the shape, among other things. This relation can be used to help explain why small mammals easily survive falls that would seriously injure or kill a human. (Round your answers to two decimal places.) (a) A 5-foot woman is 20 times as long as a 3-inch mouse (neglecting the tail). How does the terminal velocity of a woman compare with that of a mouse? The terminal velocity of the woman is ________ times that of the mouse? (b) If the 5-foot woman has a terminal velocity of 120 miles per hour, what is the terminal velocity of the 3-inch mouse? (unit is mph)(c)…
