Q1.1 An attacker at the base of a castle wall 3.65 m high throws a rock straight up with
speed 7.40 m/s from a height of 1.55 m above the ground.
3.65 m
1.55 m
a. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches
the top. If not, what initial speed must it have to reach the top?
b. To defend the castle, a rock is thrown downwards from the top of the wall with an
initial speed of 7.40 m/s. What is this rock's speed as it passes the height of 1.55 m
from the ground?
c. Does the change in speed of the downward moving rock agree with the magnitude
of the speed change of the rock moving upward between the same elevations? Explain
physically why it does or does not agree.
