1- An electric train in Japan reaches a speed of 50 m / s in 4 seconds. If the train experiences an MRUA ...
a) Calculate the acceleration with which the train travels
b) If the constant acceleration is maintained for two more seconds, how many meters does the train travel in total during the MRUA?

2- A vehicle traveling at 10 m / s begins to accelerate steadily until it reaches 25 m / s in 7 seconds.
a) Calculate the acceleration with which the car travels
b) If the car had already traveled 15 meters, in what position is it at the moment it reaches 25 m / s of speed?

3-An airplane reaches a speed of 60 m / s before taking off, traveling a distance of 800 meters from the runway. If it started from rest and it took 7 seconds to take off.
a) Calculate the constant acceleration experienced during the journey
b) Calculate the distance traveled in the last second

3- A vehicle traveling at 20 m / s must reduce its speed to 10 m / s to pass over a bridge. If you perform the operation in 6 seconds
a) How many meters did he travel in that time?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
