Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their

Chug 1-5 1. Calculate the resultant velocity of an airplane that normally flies at 200 km/h if it encounters a 50 km/h tailwind. If it encounters a 50 km/h headwind? 200+50=250km/h 200-50=150km/h 2. Calculate the resultant of the pair of velocities 100km/h north and 75 km/h south. Calculate the resultant if both of the velocities are directed north. 100+75=175km/h 100-75=25km/h 3. Calculate the magnitude of the resultant of a pair of 100 km/h velocity vectors that are at right angles to

Physics 211 Experiment #4 Newton’s Second Law – Atwood’s Machine Newton’s second law (FNET = ma) can be experimentally tested with an apparatus known as an “Atwood’s Machine” (See Figure 1.) Two weights of unequal mass‚ connected by a thread‚ are draped over a pulley‚ as shown in the figure. When released‚ the larger mass accelerates downward and the smaller one accelerates upward. Figure (1a): The Atwood’s Machine‚ showing the pulley and the two masses after a run. Figure (1b): A close

Company X Problem Analysis Through extensive analysis from the customer satisfaction surveys‚ and research from the satisfaction task force‚ Company X found three major problems areas. The company’s programs reflect poor quality‚ the development times are taking longer than the projected due dates and a small portion of employees are discrediting the company name and values. Each of these problems has contributed to the main problem; the increasing rate at which Company X is losing customers

or how far she fell. I assumed that she fell about 20 stories‚ or 200 feet (61 meters). If the absence of air resistance is assumed‚ you can find her final velocity using the equation: We know her initial velocity was 0 m/s‚ acceleration due to gravity is 9.8 m/s^2‚ and she fell 61 meters. After plugging in these values‚ the final velocity was determined to be 34.6 m/s. To put this in terms that can be visualized‚ Lois Lane was falling at a speed of about 77mph when superman caught her. I then
