Concept explainers
Parachutists whose chutes have failed to open have been known to survive if they land in deep snow. Assume that a 75-kg parachutist hits the ground with an area of impact of 0.30 m2 at a velocity of 55 m/s, and that the ultimate strength of body tissue is 5 × 105 N/m2. Assume that the person is brought to rest in 1.0 m of snow. Show that the person may escape serious injury.

- Why is it preferable for airplanes to take off into the wind rather than with the wind?arrow_forwardA host pours the remnants of several of wine into a jug a party. The host then inserts a cork with a 2.00-cm diameter into the bottle, placing it in direct contact with the wine. The host is amazed when the host pounds the cork into place and the bottom of the jug (with a 14.0-cm diameter) breaks away. Calculate the extra force exerted against the bottom if he pounded the cork with a 120-N force.arrow_forwardA horizontal pipe 10.0 cm in diameter has a smooth reduction to a pipe 5.00 cm in diameter. If the pressure of the water in the larger pipe is 8.00 104 Pa and the pressure in the smaller pipe is 6.00 104 Pa, at what rate does water flow through the pipes?arrow_forward
- When a person feels that he is about to fall, he will often put out his hand to try to break the fall. Explain why this natural reaction usually leads to bruises or minor broken bones such as in the wrists instead of major broken bones such as the skull.arrow_forwardA bunch of needles fell on a basket of feathers. What is the best method to do to separate the needles from the feathers without hurting yourself? Give a brief and exact explaination.arrow_forwardFind the settling velocity of a 20 microm diameter particle with density 1500 kg/m^3. If this particle had been hurled to a height of 8,000 m during a volcanic eruption, estimate the time required to reach the ground (sea level). You many assume that the viscosity of air does not change enough to worry about. If winds average 10 m/s, how far away would it blow on its way down?arrow_forward
- As a hiker in Glacier National Park, you are looking for a way to keep the bears from getting at your supply of food. You find a campground that is near an outcropping of ice from one of the glaciers. Part of the ice outcropping forms a slope of angle ? up to a vertical cliff. You decide that this is an ideal place to hang your food supply, as the cliff is too tall for a bear to reach it. You put all of your food into a burlap sack, tie an unstretchable rope to the sack, and tie another bag full of rocks to the other end of the rope to act as an anchor. The mass of rocks that you put into the anchor bag is equal to the mass of food in the other bag. What will be the acceleration ? of the food bag when you let go of the anchor bag? Assume that the weight of the rope is negligible, and that the ice can be considered frictionless. Express the resulting acceleration ? of the food bag in terms of ? and ?, the acceleration due to gravity. Let the positive direction for this bag be downwards.arrow_forwardA trough with a trapezoidal cross-section, as shown in the figure, contains vegetable oil with density 910 kg/m3. (Use g = 9.8 m/s2 for the acceleration due to gravity.) 3 m 2 m 4 m 1 m A trough has a trapezoidal cross section. The vertical side is 3 m in height. There are two horizontal sides perpendicular to the vertical side, with the larger horizontal side being at the top and 2 m long, and the shorter side at the bottom is 1 m long. The width of the trough is 4 m. (a) Find the hydrostatic force (in N) on one end of the trough if it is completely full of oil. (b) Compute the force (in N) on one end if the trough is filled to a depth of 1.8 m. (Round your answer to two decimal places.)arrow_forward
