The tree was 26.5 m tall.
rule is:average speed = distance/time taken=95inches/56 hundredths of a second=95/0.56=169.6428571 inch/second
Ignoring any effects due to air resistance, the speed of the stone is zero at the instant it's dropped, and increases steadily to 78.98 meters per second when it hits the ground. The velocity is directed downward throughout the experiment.
You need the amount of time that it took to fall the 45m.
Potential energy refers to the energy of an object that is released as kinetic energy when it falls back to the ground. When a stone is dropped from a height of 5m, its speed when it hits the ground is 9.9 m/s.
Ignoring air resistance, the acceleration is constant, from the moment the ballleaves the hand until the moment it hits the ground, regardless of the mass ofthe ball or the height from which it's released.It's 9.8 meters (32.2 feet) per second2 . That's the acceleration of gravity. (On Earth.)The speed of a dropped object grows continuously. At the end of 1 second,it's 9.8 meters (32.2 feet) per second.

Yes.
A) the dropped one hits the ground first B) the tossed one hits harder

both reaches the ground at the same time because in the moon there occurs free fall.
