To calculate the distance covered by a body with constant acceleration, you can use the following formula:
Distance (s) = Initial velocity (u) * time (t) + 0.5 * acceleration (a) * time squared (t^2)
Given that the body has a constant acceleration of 5 m/second^2, we can assume an initial velocity of 0 m/second since it is not specified in the question. Therefore, the formula becomes:
Distance (s) = 0 * 5 + 0.5 * 5 * (5^2)
Calculating the values within the parentheses first:
Distance (s) = 0 + 0.5 * 5 * 25
Multiplying 0.5 by 5 and 25:
Distance (s) = 0 + 0.5 * 125
Distance (s) = 0 + 62.5
Finally, we find that the distance covered by the body in the 5th second is 62.5 meters.
