EXERCISE 6 1. A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25° downward from the horizontal. Find the work done by the shopper as she moves down a 50-m length of aisle. 1.6 kJ 2. A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed‚ find (a) the work done by the 150-N force and (b) the coefficient of kinetic friction between the crate and surface. 900J

develop a two-week personal exercise plan. In my two- week fitness plan‚ I discuss the FITT principle‚ which stands for frequency‚ intensity‚ time‚ and type. Frequency involves how often I would perform the physical activity. Intensity is how hard I work out during my physical activity. Timing is the length‚ or how long I plan to work out and the last T in the FITT principle stands for the type of exercise I want to do‚ such as cardio or strength training. I incorporated FITT into my two-week personal

Problem-Solving Exercise 1 1. In your own words‚ explain what density altitude is and how it affects your airplane. Density altitude‚ or "Pressure Altitude"‚ is the density of air given as a height above Mean Sea Level (MSL). Density altitude affects the wings ability to create lift‚ the aircrafts propeller to create thrust and the power output of the engine. 2. In your own words‚ explain the theory of lift and what basic laws are involved. In my opinion lift can be explained by

Policing Paper There are many different forms of technology used in policing in today society. This technology is very important when it comes to policing and being able to do their jobs proficiently. Some of the technology they use is database and information technology‚ computer-aid dispatch‚ records management systems‚ and mobile computing. All of these forms of technology play a vital role in policing. Without these forms of technology being available to police there could be a higher crime
