At an Independence Day celebration show, a large firework is
shot from the ground and, in the first stage of its bursting
pattern, splits into two unequal parts.
Assume that the firework has a mass of m_o = 0.30 kg and is
launched from a cannon at an angle of theta_o= 48.8° with an
initial velocity of v= 20 m/s. Just as the firework reaches its
hight point in its trajectory, it explodes into two pieces.
Immediately after the explosion,...

Revie Part A In a carnival booth, you win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.45 m from this point (the figure (Figure 1)). If you toss the coin with a velocity of 5.23 m/s at an angle of 55.2° above the horizontal, the coin lands in the dish. You can ignore air...

A shell is shot with an initial velocity
of 25 m/s, at an angle of
= 57° with the horizontal. At the top of the trajectory, the shell
explodes into two fragments of equal mass (see the figure). One
fragment, whose speed immediately after the explosion is zero,
falls vertically. How far from the gun does the other fragment
land, assuming that the terrain is level and that air drag is
negligible?

For the above particle, if at t=0s, vx=-4 m/s, what is the
velocity at t=20s?
With the same condition as in previous problem, what is the
average velocity in time interval 0 to 20 s?
Yet still for the same setting, what is the average speed in
time interval 0 to 20 s?
The answer for the average speed is 9.5 m/s not 9.1 m/s like the
average velocity is and I can't firgure out why that is.

A seagull flying horizontally over the ocean at a constant speed of 2.55 m/s carries a small fish in its mouth. It accidentally lets go of the fish, and 2.30 s after the bird lets go, the fish lands in the ocean. Just before reaching the ocean, what is the horizontal component of the fish's velocity in m/s? Ignore air resistance. Assume the bird is initially traveling in the positive x direction. (Indicate the direction with the sign of your...
