Question

Calculate the Acceleration and Distance Covered if a train starts from rest and gains 20 m/s speed in 2 second.​

Answer 1

Answer:

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .

Answer 2

Answer:

It moves with acceleration = 2m/s2 for half minute ( 30 seconds). Distance covered in this time interval is given by: S=ut+½at2. =0+½×2×30×30. =900m.
