<em><u>Newton's First Law ,</u></em>
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
Answer:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.
Explanation:
Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
Mass of oxygen stays the same.
Answer:
If it falls from 32 feet, how could the distance be 29 feet? Twelve bounces later, 58 is "obviously" incorrect as well. Eliminate those two before you do anything else.
The total distance up until that the nth bounce is
Sn = (32 - 32(.8)12) / (1 - .8) = 149.004883722... = 149
