The distance covered by the body in 20 seconds is 800 meters.
Explanation:
Given that,
Initial velocity of the body, u = 0
Final velocity of the body, v = 80 m/s
Time, t = 20 s
Let a is the uniform acceleration of the body. It can be calculated using first equation of motion as :
Let d is the distance covered by the body in 20 seconds. Using the second equation of motion as :
d = 800 m
So, the distance covered by the body in 20 seconds is 800 meters.
