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 velocity?
A student begins at rest and then walks north at a speed of v1=0.65m/s. The student then turns south and walks at a speed of v2=0.28m/s. Take north to be the positive direction. a)What is the student's overall average velocity vavg, in meters per second, for the full trip assuming the student spent equal times at speeds v1 and v2? b) If the student travels in the stated directions for 30.0s30.0s at speed v1 and 20.0s at speed v2, what is the net displacement, in meters, during the trip? c) If it takes the student 1.2s to reach the speed v1, from rest, what is the magnitude, in meters per squared second, of the student’s average acceleration during that time?
A motor car is moving with initial velocity in the x-direction at 30 m/s. After 30 s, the car applies its brakes steadily to slow down the car to a velocity of 10 m/s in 12 s. The continues onward for 10 s more. How far in m did the car travel for the full 52 s? Report your answer to three sig figs, you don't need to write "m". HINT: Break up the problem into three stages - 30s, 12s, and the final 10s. During the 12 s, you'll need the acceleration.
I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.
You drive your car from home to school at an average speed of 60 kph East for 1 hr and then continue 80 kph North for 1.5 hrs. 1. What is your average speed for the entire trip?
An object is thrown straight up with an initial velocity of 16 m/s. a) How high does it go in meters? b) How long is it in the air in seconds?
Osama was testing his new car by racing with his fiend Adam, Osama was driving at 54.0 mile/hr, enters a one-way narrow subway. Osama then observed a Truck 100 m ahead traveling at a low constant speed 3.00 m/s. Osama used his brakes but can accelerate only at -2.00 m/s2 because the road was wet. Will there be an accident? Explain. If yes,Page 5 of 85at what time the accident occurs and how far into the subway. If no, determine the distance of closest approach between Osama’s car and the Truck. (1mile=1609m).

The hare goes very fast for brief intervals, but stops frequently, whereas the t hare. (a) Which of the two racers has the greater average speed over the duration of the race? OThe tortoise has the greater average speed since he was the winner. The hare has the greater average speed since he can go faster. Their average speeds are equal. OIt's impossible to determine who had the greater average speed without collecting data. (b) Which of the two racers is likely to reach the greatest instantaneous speed during the race? OThe tortoise has the greater instantaneous speed since he was the winner. OThe hare has the greater instantaneous speed since he can go faster.
