To calculate the acceleration of the body, we can use the formula:
Acceleration = (Change in Velocity) / (Time taken)
Given that the body starts from rest (initial velocity, u = 0 m/s) and acquires a velocity of 10 m/s (final velocity, v = 10 m/s) in 2 seconds (time taken, t = 2 s), we can substitute these values into the formula:
Acceleration = (10 m/s - 0 m/s) / (2 s)
Acceleration = 10 m/s / 2 s
Acceleration = 5 m/s²
Therefore, the acceleration of the body is 5 m/s².
