To calculate the time it takes for an object to fall 5 meters from rest with a gravitational acceleration of 10 m/s², the equation Y = Yo + Vot + 1/2at² can be used. Given that the initial velocity (Vo) is 0, the equation simplifies to Y = 1/2at². Substituting the values, 5 m = 1/2(10 m/s²)t² leads to t² = 1, resulting in t = 1 second. Therefore, it takes 1 second for the object to fall 5 meters from rest. This calculation demonstrates the relationship between distance, acceleration, and time in free fall scenarios.
