HOMEWORK PROBLEMS Chapter 4: THE LAWS OF MOTION PART-A: Hand in your answers in class on scantron on Wednesday 22 September-2010. The questions have been numbered so you can use the back side of an older scantron. Write your name‚ class (1401) and HW # 4 on the scantron. 1. A horizontal force of 95.0 N is applied to a 60.0-kg crate on a rough‚ level surface. If the crate accelerates at 1.20 m/s2‚ what is the magnitude of the force of kinetic friction acting on the crate? (a) 23.0 N (b) 45.0 N

------------------------------------------------- The Mondragon Experiment * Government * Econ By Greg MacLeod | April 4‚ 2009 | 10:28 PM The concept of the corporation reaches back to Roman times. However‚ the modern business corporation evolved radically from its ancient roots into a form with little relation to the purpose as understood by historians of law. Today‚ the typical business corporation seems to be a disjointed entity whereby shareholders seek maximum income‚ labor unions

CASE: Research in Motion (RIM) Introduction Research In Motion (RIM) is the company behind BlackBerry‚ one of the best-selling smartphone brands in the US. RIM first went public in 1997 and introduced BlackBerry as a paging device that allowed user to read emails. Soon‚ BlackBerry evolved into a full blown smartphone: a call‚ text‚ email capable organizer. It first gained ground in the business community and government‚ with its high-se curity and essential business features. BlackBerry was

Kevin Doherty Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering

the floor. Explain how the motion of the car after you released the end of the straw demonstrates Newton’s three laws of motion. •Newton’s three laws of motion. Newton’s First Law of Motion states‚ “Every object continues in a state of rest‚ or in motion in a straight line at constant speed‚ unless it is compelled to change that state by an unbalanced force exerted upon it.” The change was the thrust made when the straw was released. •Newton’s Second Law of Motion states‚ “The acceleration produced

Exercise 1: Rectilinear Motion Background The average accelerations of a US Navy fighter jet takeoff to an US Air Force fighter jet takeoff are very different. The aircraft conditions are the same except the Air Force fighter is on a 12‚000-ft dry concrete runway and the Navy fighter is on the catapult of an aircraft carrier. (Hint: You will have to use two different methods because you are not given the catapult force‚ but you have the catapult distance. Assume aircraft is airborne after the catapult

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of
