The Shanghai Maglev train can travel at speeds up to 431[km=hr]. The Pudong International Airport is approximately 18:6[miles] away from a very popular train stop. Assuming the train has an average speed during a trip from the train stop to the airport of 250[km=hr], how long will it take to make the trip [minutes]. Assuming the train can accelerate to its fastest speed in 5[s], determine the average acceleration in [m=s2] and g's Research how many g's the human body can experience prior to passing out, and determine the speed the train would have to achieve in 5[s] to create this threshold level of g's. Assuming it's 17 G's for the max threshold.
The power needed to operate your body is about 100 {rm watts}. Suppose your body could run on fusion power and could convert a total of 0.7 of its mass into energy. How much energy would be available through fusion? Assume the mass is 70kg.
A 0.025 kg golf ball moving at 21.0 m/s crashes throughout the window of a house in 2.0 10-4 s. After the crash, ball continues in the same direction with a speed of 10 m/s. assuming the force exerted on the ball by the window was constant, what w..
