2: Acceleration 2 Name: Date: Period: UNIT I Acceleration 2 The problem v vs t graph Solution 1. A poorly tuned Yugo can accelerate from rest to a speed of 28 m/s in 20 s. a) What is the average acceleration of the car? b) What distance does it travel in this time? a = (28-0m/s)/20s = 1.4 m/s/s x = 1/2at2 = ½(1.4)(20)2= 280m 2. At t = 0 a car has a speed of 30 m/s. After 6 s‚ its speed is 15 m/s. What is its average acceleration during this time interval? a

storyline of the film Modern Times revolves around the two characters‚ a factory worker and street rogue‚ played by Charlie Chaplin and Goddard respectively‚ who fall short to take part into the modern and mechanized world. There were several themes clearly emphasized in the beginning of the film; the workers are portrayed as mere followers‚ no distinctiveness‚ merely considered as moving parts in the economic system. The two main characters were seen as being non-conformant. Time as shown in the beginning

HBS 2.2.3. Reaction Time Experimental Design I. Identify a Problem or Question: Can the reaction of an individual be affected by other external factors? II. Introduction: Reaction time refers to the amount of time it takes for a person to process and react to a stimulus. It is important in everyday activities‚ such as driving‚ and sports‚ but not much experiment is conducted to research on this matter. Reaction time with its practical implication can leads to great consequences‚e.g. d

How much is it? How does reaction time change with practice? THEORETICAL The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction

As mentioned‚ our results suggest that the distraction times vary greatly on different individual factors. However‚ with the overall averages at 237 for no distractions compared to 315 for distractions‚ our team’s hypothesis still holds true that distractions greatly affect reaction time. Our experiment demonstrated to us that there are two factors intertwined in influencing reaction time: the distraction itself and the individual’s ability to react while distracted. For example‚ a cellphone app

Nicotine and Reaction Time Introduction: Nicotine is a drug‚ nerve poison‚ sedative and also a stimulant. It is said to have stimulating and relaxing effects‚ but it depends on the dosage of nicotine. As it was mentioned above‚ Nicotine is both a stimulant and a sedative; this means that straight after you have ingested nicotine‚ it gives you an adrenaline rush and also helps you to relax afterwards i.e. crash. This means that if I conduct my experiment straight after the smokers have ingested nicotine

How do sports drinks affect reaction time? My goal was to test different drinks that are advertised to help you have a better athletic performance‚ and to find out which one worked best. Procedure: 1. I measured each test subject’s reaction time prior to exercise for comparative measures. 2. I divided each 1200ml portions of Gatorade‚ Powerade‚ and Water into 300ml portions respectively. 3. I had each test subject take one of the drinks and go on a 30min run. I then‚ instructed the subjects
