Answer:
Explanation:
Let's use the kinematic equation
s = ut + ½at²
Where
s = distance fallen
u = initial velocity
t = time taken
a = acceleration
Here the hammer is dropped so a = g = gravitational acceleration
u = 0 because the hammer is dropped.
So by substituting you get,
1000 = 0 + ½×10×t²
t² = 200
t = 14.14 s
This is a true and false question correct or did you accidentally put two truths ??
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
Answer:
True
True statement:

Answer:
B. develop hypotheses that will be subjected to empirical test.
Explanation:
The rational method of inquiry is most useful in the early stages of science to develop hypotheses that will be subjected to empirical test.
