Answer:
40.1m/s
Explanation:
This is a kinematics problem
x = 82m
a = -9.8m/s^2
v(initial) = 0
Find: v(final)
Using kinematics equation:
vf^2 = vi^2 + 2a(delta)x
vf^2 = 0 + 2*(-9.8)*(82)
vf = sqrt(1607.2) = 40.09m/s
The is traveling with a velocity of 40.1m/s when it hits the ground.
Answer:
First law: An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force. (i.e. Objects in motion tend to stay in motion. Objects at rest tend to stay at rest.)
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
Explanation:
Answer:
2, less than the change in momentum

Examples of inclined planes are ramps, sloping roads and hills, plows, chisels, hatchets, carpenter's planes, and wedges.
Because there is no wind, rain, snow, sleet, or people to wear them down,
and no rivers, streams, or floods to cover them over.
