عندي 3 أسئلة جابوا لي وجع رأس أريد أن أن يساعدني على حله ويخبرني الطريقة ضروري أن تكون الإجابة اليوم...وشكراً عموماً
If the maximum acceleration that is tolerable for passengers in a subway train is 1.34 m/s2 and subway stations are located 781 m apart. What is the maximum speed a subway train can attain between stations? Give the answer in m/s and give three significant figures
An electron has a constant acceleration of +2.3 m/s2. At a certain instant its velocity is +9.6 m/s. What is its velocity 2.23 s earlier? Give the answer in m/s and give two significant figures only
If the maximum acceleration that is tolerable for passengers in a subway train is 1.34 m/s<sup>2</sup> and subway stations are located 806 m apart. If a subway train stops for 20 s at each station, what is the maximum average speed of the train, from one start-up to the next. Give the answer in m/s and give three significant figures
