OBINPHYS8 2.Q.016.

An archer aims an arrow exactly horizontal over a flat field and shoots it. At the same instant, the archer's watchband breaks

and the watch falls to the ground. Does the watch hit the ground before, at the same time as, or after the arrow hits the

ground?

before

at the same time

after

Defend your answer.

The watch will hit the ground before the arrow because the velocity of the arrow is mostly horizontal while the velocity

of the watch is entirely vertical.

The watch will hit the ground before the arrow because the total distance the watch travels before it hits the ground is

less than the total distance the arrow travels.

The watch will hit the ground after the arrow because the arrow has a large initial velocity while the initial velocity of the

watch is zero.

The watch and the arrow hit the ground at the same time. The vertical acceleration of the arrow is the same as that of

the watch because horizontal motion does not affect vertical motion.
