Suppose a 10.0 kg fireworks shell is shot into the air with aninitial velocity of 69.0 m/s at an angle of 80.0° above thehorizontal. At the highest point of its trajectory, a smallexplosive charge separates it into two pieces, neither of whichignite (two duds). One 9.00 kg piece falls straight down, havingzero velocity just after the explosion. Neglect air resistance (apoor approximation, but do it anyway).
(a) At what horizontal distance from the starting point does the9.00 kg piece hit the ground?
m
(b) Calculate the velocity of the 1.00 kg piece just after theseparation.
m/s
(c) At what horizontal distance from the starting point does the1.00 kg piece hit the ground?
m
