<em>Distance = 50 meters</em>
Explanation:
<u>Constantly Accelerated Motion</u>
When the velocity of a moving object changes at a constant rate, called acceleration, the velocity changes in same amounts in the same times. The question has a mistake when asking when the acceleration is 20 m/s. If the acceleration is constant, the only variable that can change to that value is the velocity. The equation to calculate the speed is
And the distance s is
Given the object starts from rest, vo=0 and vf=20 m/s at . We compute t
Now we compute s
