To find the acceleration, we can use the formula:
acceleration (a) = (final velocity (v_f) - initial velocity (v_i)) / time (t)
Given: Initial velocity (v_i) = 20 m/s Final velocity (v_f) = 30 m/s Time (t) = 2 seconds
Plugging in the values:
a = (30 m/s - 20 m/s) / 2 s a = 10 m/s / 2 s a = 5 m/s²
Therefore, the acceleration of the body is 5 m/s².
To find the distance covered, we can use the formula:
distance (d) = (initial velocity (v_i) + final velocity (v_f)) / 2 * time (t)
Plugging in the values:
d = (20 m/s + 30 m/s) / 2 * 2 s d = 50 m/s / 4 s d = 12.5 m
Therefore, the distance covered by the body is 12.5 meters.
