Answer:
(A) 7 m/s
Explanation:
Given:
Initial velocity = 1 m/s (u)
Acceleration = 0.5 m/s² (a)
To find:
Velocity when displacement is 48 m, so:
s= 48 m
V = (unknown)
So, here we can use the third equation of motion which says:
So, substituting the values, we get;
The velocity of the train when displacement is 48 metres is equal to 7m/s
Option (A) is the right answer
