Answer:
the first equation of motion
v = u+at
after putting values in the equation
60 = 2+(a)7
a = 58/7
a = 8ms^-2

Answer:
8.285 m/s²
Explanation:
Given :
- Initial velocity of the train = u = 2 m/s
- Time taken by the train = t = 7 seconds
- Final velocity of the train = v = 60 m/s
To find :
- Acceleration of the train
Using the first equation of motion which says :
V=u+at
60=2+a(7)
60 = 2+7a
60-2 = 7a
58 = 7a
a = 58/7
a = 8.285 m/s²
The acceleration of the train in the above question is equal to 8.285 m/s²
