The height (sidewalk to roof) of notable tall buildings in
America is compared to the number of stories of the building
(beginning at street level).
Height: 1050, 428, 362, 529, 790, 401
Number of stories: 57, 28, 26, 40, 60, 22
If you can make predictions, when the height is 600, what is
the number of stories? Please answer with a whole number (no
decimal places). If you can’t make a prediction, put “none” in the
answer box.

Part A) Two
identical pieces of machinery are lifted from the sidewalk to the
roof of a 100.0 m tall building. One is lifted directly to the
building's roof and has a change in internal energy of 1059 kJ. The
other is lifted to twice the height of the building and then
lowered to the roof. What is the change in internal energy of the
second piece of machinery once it has reached the roof?

A ball is thrown upwards from the roof of a house that is 20m
tall. The initial velocity V0 is 10m/s, and the
acceleration due to gravity g is 10m/s2.
Find:
a) The maximum height that the ball reaches in the air.
b) The total time of flight.
c) The hitting velocity (the velocity right before the ball hits
the ground).
d) Its velocity at t=2s.
A man stands on the roof of a 10.0 m -tall building and throws a
rock with a velocity of magnitude 30.0 m/s at an angle of 42.0 ∘
above the horizontal. You can ignore air resistance.
A. Calculate the maximum height above the roof reached by the
rock
B. Calculate the magnitude of the velocity of the rock just
before it strikes the ground

A baseball is thrown from the roof of 23.5 m -tall building with
an initial velocity of magnitude 10.5 m/s and directed at an angle
of 52.4° above the horizontal.
