A skydiver of mass m = 70 kg, which includes the mass of all the equipment she is wearing (helmet, parachute, etc.), jumps from an airplane at high altitude. The density of the air is ρ = 1.22 kg/m3 .

(a) Estimate a numerical value for the terminal speed of the diver while she is in a horizontal spread-eagle formation. (Parachute is not open.) The drag coefficient of the diver in this formation is about 1.0. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(b) Estimate a numerical value for the terminal speed of the diver while she is in a head first vertical dive. (Parachute is not open.) The drag coefficient of the diver in this formation is about 0.70. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(c) Estimate a numerical value for the terminal speed of the diver when her parachute is open. The drag coefficient of the diver in this formation is about 1.75. Any other needed quantities should be estimated. Show your starting formulas and all your work.

A mountain climber of mass m=75.0 kg slips during a climb and begins to fall freely. She forgot her rope and had to use an ideal spring. The spring is hanging vertically with an unstretched equilibrium position at the origin, x=0. On her descent, she grabs the end of the spring which has a spring constant of k= 981 N/m. Ignore friction, air resistance, and any other dissipative effects. a) The climbers velocity when she grabbed the spring was 20.0...

Space X launches a rocket of mass m off the edge of a cliff of height h . The rocket produces a constant thrust force of unknown magnitude that is directed at an angle θ above the horizontal. Unfortunately, the rocket crashes into the ground a distance d from the base of the cliff. Determine the magnitude of the rocket’s thrust force and the speed of the rocket when it crashed. You should also include a graph of the position...

Based on the following: The estimated purchase price for the equipment required to move the operation in-house would be $500,000. Additional net working capital to support production (in the form of cash used in Inventory, AR net of AP) would be needed in the amount of $25,000 per year starting in year 0 and through all 5 years of the project to support production. The current spending on this component (i.e. annual spend pool) is $875,000. The estimated cash flow...

Your corporation is faced with the decision of which Word Processor to purchase for its manuscript typing pool (think ‘Mad Men’ here). It can buy the Hack brand processor software package at an aggregate (multi-copy licenses) up-front expense of $80,000, which would also require $20,000 in annual year-by-year maintenance/upkeep expenses. Hack initial cost would be depreciated on a straight-line basis to z ZERO terminal book balue at the end of its four-year useful life. This package’s software and supporting hardware...

Please answer all not understanding: 1. Volumetric expansion coefficients of simple materials are often well catalogued. However, the thermal expansion coefficient β of a human body is less well known. This could affect the human body\'s specific gravity and, therefore, measurements of its body/fat ratio. Suppose that a human body of weight w0 (on dry land) is placed on a scale while completely immersed in formaldehyde of temperature T1. Once the temperature increases by ΔT, the scale reading drops by...

Melinda Baker had recently been transferred to the Home Security Division of ADP. Shortly after taking over her new position as controller, she was asked to develop the division’s predetermined overhead rate for the upcoming year. The accuracy of the rate is important because it is used all year long and any overapplied or under- applied overhead is closed out to Cost of Goods Sold at the end of the year. ADP uses direct labor-hours as the allocation base for...
