Part one:
a gust of wind blows an apple from a tree.
as the apple falls, the force of gravity on the
apple is 9.39 n downward, and the force of
the wind on the apple is 1.50 n to the right.
what is the magnitude of the net external
force on the apple?
answer in units of n.

part two:
what is the direction of the net external force
on the apple (measured from the downward
vertical, so that the angle to the right of
downward is positive)?
answer in units of ◦

Ways that industry and agriculture use physical properties to separate substances

The energy released by a nuclear fusion reaction is produced when

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
