Take the stone's position at ground level to be the origin, and the downward direction to be negative. Then its position in the air at time is given by
Let be the depth of the well. The stone hits the bottom of the well after 5.00 s, so that
Average velocity over a given time interval is the distance traveled divided by the time:
Answer: The train traveled 210 miles in 6 seconds of time duration.
Explanation:
The initial velocity of the train,u = 50 mile/s
Acceleration of the train ,a =
Duration of time ,t = 6 seconds
Using second equation of motion :
The train traveled 210 miles in 6 seconds of time duration.
