Suppose a 10.0 kg fireworks shell is shot into the air with an initial velocity of 69.0 m/s at an angle of 80.0° above the horizontal. At the highest point of its trajectory, a small explosive charge separates it into two pieces, neither of which ignite (two duds). One 9.00 kg piece falls straight down, having zero velocity just after the explosion. Neglect air resistance (a poor approximation, but do it anyway).
(a) At what horizontal distance from the starting point does the
9.00 kg piece hit the ground?
m
(b) Calculate the velocity of the 1.00 kg piece just after the
separation.
m/s
(c) At what horizontal distance from the starting point does the
1.00 kg piece hit the ground?
m

Suppose a 13.0 kg fireworks shell is shot into the air with an
initial velocity of 62.0 m/s at an angle of 80.0° above the
horizontal. At the highest point of its trajectory, a small
explosive charge separates it into two pieces, neither of which
ignite (two duds). One 9.00 kg piece falls straight down, having
zero velocity just after the explosion. Neglect air resistance (a
poor approximation, but do it anyway). A)At what horizontal

During a fireworks display, a shell is shot into the air with an
initial speed of 91.55 m/s at an angle of theta degrees above the
horizontal. The fuse is timed to 8.21 seconds for the shell just as
it reaches its highest point above the ground. If the horizontal
displacement of the shell is 149.68 meters when it explodes, what
is the height (in unit of meters) when the shell explodes?
You must use g = 9.8 m/s2.

In the shot put, a heavy lead weight—the "shot"—is given an
initial velocity, starting from an initial elevation approximately
equal to the shot putter's height, say, 2.00 m. If v0 = 7.05 m/s,
find the horizontal distance traveled by the shot for the following
initial angles above the horizontal.

initial velocity, starting from an initial elevation approximately
equal to the shot putter's height, say, 2.00 m. If
v0 = 7.90 m/s, find the horizontal distance
traveled by the shot for the following initial angles above the
horizontal. (a) θ0 = 0°

Problem 3.29
A shot-putter throws the "shot" (mass = 7.3 kg ) with an initial
speed of 14.5 m/s at a 37.0 ∘ angle to the horizontal.
Part A
Calculate the horizontal distance traveled by the shot if it
leaves the athlete's hand at a height of 2.15 m above the
ground.
Express your answer using three significant figures and include
the appropriate units.
