Passage Problems
Alice (A), Bob (B), and Carrie (C) all start from their dorm and head
for the library for an evening study session. Alice takes a straight path,
below the horizontal, and land 55 m horizontally from the end of
the jump. Your job is to specify the slope of the ground so skiers'
trajectories make an angle of only 3.0° with the ground on land-
ing, ensuring their safety. What slope do you specify?
T 9.5°
-55 m

If Thor wants to reach escape velocity (velocity needed to leave Earth’s atmosphere), he will need the linear velocity of the center of mass of the hammer to be 11,200 m/s. Thor's escape velocity is 33532.9 rad/s, the angular velocity is 8055.5 rad/s^2.
