Question

# A 25-newton weight falls freely from rest from the roof of a building. what is the total distance the weight falls in the first 1.0 second?

Answer

4.9m

- Identify the values given. A: mass (m) = 25N, initial velocity (v0) = 0, time (t) = 1.0s, acceleration due to gravity (g) = 9.8m/s^2.
- Use the kinematic equation: d = v0t + 1/2(at^2) to find the total distance the weight falls.
- Plug in the values to the equation: d = (0)(1.0) + (0.5)(9.8)(1.0)^2. A: d = 4.9m.
