The Fastest (and Most Expensive) Car! The table shows test data for the Bugatti Veyron Super Sport, the fastest street car made. The car is moving in a straight line (the x -axis). (a) Sketch a vx-t graph of this car’s velocity (in mi/h) as a function of time. Is its acceleration constant? (b) Calculate the car’s average acceleration (in m/s2) between (i) 0 and 2.1 s; (ii) 2.1 s and 20.0 s; (iii) 20.0 s and 53 s. Are these results consistent with your graph in part (a)? (Before you decide to buy this car, it might be helpful to know that only 300 will be built, it runs out of gas in 12 minutes at top speed, and it costs more than $1.5 million!)
Physics Electricity and Magnetism (Professor Perdekamp) : Week 1 Notes Prelecture: Coulomb’s Law Electric Charge Gravity Electric Charge What is charge Electric charge is responsible for electric forces. Two kinds of electric charge: positive and negative Two kinds of electric force: attractive and repulsive Note: this is in contrast to gravitational force where mass only attracts Building Blocks of Matter Conductors: Insulators: Electrons free to move Electrons don’t/cannot move (metals) (plastics) Coulomb’s Law (1785) ex) r^ determines direction F1,2nd F 2,1Newton’s 3rd Law pairs! If the resultant number is: positive → force is repulsive negative → force is attractive Uni
