Question
A ball is thrown with an initial velocity of 100. m/s at an angle of 60.0⁰
above the horizontal. If air resistance and wind are neglected, the x- and
y- components of the initial velocity are
86.6 m/s and 50.0 m/s, respectively.
O 50.0 m/s and 86.6 m/s, respectively.
90.0 m/s and 52.0 m/s, respectively.
O 41.0 m/s and 90.0 m/s, respectively,

If you are standing on a weighing scale attached to the floor of an elevator
of a building and you see that the scale reading is zero, then the elevator
is
O accelerating upward.
O moving at constant velocity.
O not moving.
O freely falling.
