At the instant shown, Speedboat A has more momentum than Speedboat B. Is the net force on Speedboat A greater than, less than, or equal to the net force on Speedboat B? Explain. (They are equal since the net force on both boats is zero. Since the speedboats are moving with constant speed and direction, there is no acceleration, so the net force is zero)Which is the formula that describes the magnitude of impulse on an object?

Early in the twentieth century, Robert Goddard proposedsending a rocket to the moon. Critics objected that in avacuum, such as exists between the Earth and the Moon,the gases emitted by the rocket would have nothing topush against to propel the rocket.
