Suppose a rocket is being launched from the Kennedy Space Center. The rocket motors are ignited and the rocket begins to climb into space. According to Newton's 3rd Law, which of the following explains the flight?
The rocket pushes against the ground and the ground pushes against the rocket.

The ball from problem 3 falls off the top of the building. What is the ball's kinetic energy just before it hits the ground?
Zero Joules because it is at ground level.
The answer depends on the temperature of the surroundings.
Less than the answer to problem 3, but more than zero.
The same as the answer from problem 3.

A bullet is fired horizontally from a rifle and another is simultaneously dropped from the same height as the rifle. Which bullet strikes the ground first?
the bullet from the rifle because it has a greater horizontal velocity
the bullet dropped because it travels the least amount of vertical distance
the bullets fall at the same rate because when a bullet is fired it has less mass
the bullets fall at the same rate because gravity causes both bullets to fall at 9.81m/s2
the bull dropped because it has a lower temperature than the bullet fired

acceleration stays the same
acceleration becomes 2x greater
force cancels the acceleration
