To find the distance covered by the body in 2 seconds when accelerating at a constant rate of 10 m/s², we can use the equation of motion:
distance (d) = initial velocity (u) * time (t) + (1/2) * acceleration (a) * time squared (t²)
Given that the body starts from rest, the initial velocity (u) is 0 m/s. The acceleration (a) is 10 m/s², and the time (t) is 2 seconds. Plugging these values into the equation, we can calculate the distance covered:
distance (d) = 0 * 2 + (1/2) * 10 * 2² distance (d) = 0 + (1/2) * 10 * 4 distance (d) = 0 + 20 distance (d) = 20 meters
Therefore, the body will cover a distance of 20 meters in 2 seconds when accelerating at a constant rate of 10 m/s², starting from rest.
