Question 6 (2 pt): The Shanghai maglev train connects Longyang Road to Pudong International Airport, a distance of 30 km. The journey takes 8.50 minutes on a particular day. What is the maglev train's average speed (in km/h)?
The Shanghai maglev train connects Longyang Road to Pudong International Airport, a distance of 30 km. The journey takes 8 minutes on average. What is the maglev train's average speed and velocity? A particle moves along the x-axis according to x(t) = 10t - 2t^2 m. (a) What is the instantaneous velocity at t = 2 s and t = 3 s? (b) What is the instantaneous speed at these times? (c) What is the average velocity between t = 2 s and t = 3 s?
