A 7.7 kg firework is
launched straight up and at its maximum height 13 m it explodes
into three parts. Part A (1.5 kg) moves straight down and lands
0.23 seconds after the explosion. Part B (2 kg) moves horizontally
to the right and lands 6.5 meters from Part A. Part C moves to the
left at some angle. How far from Part A does Part C land ?(no
direction needed)

A firework is launched straight upward from a height of 1 meter. The acceleration function for the firework is given below: a(t) = e^t + cos(t) meters per second squared where t is time since thefirework launched. (a) Find the velocity and position functions for the firework. (b) What is the net change of thefirework's position after 3 seconds?

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,...

A projectile of mass M #13.4 kg is launched over level ground at a speed 28.6 and at an angle of 46.5 degrees above the horizontal. At the instant that the projectile is at what would be its highest point it explodes into two pieces; after the explosion there is a piece of mass ml = 5.2kg which has a vertical component of velocity of 9.7 , and a second piece of mass m2 which moves downwards. The explosion does...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...

Problem 7 4.A projectile of mass 9.6 kg is launched from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal (see the figure). At some time after its launch, an explosion splits the projectile into two pieces. One piece, of mass 6.5 kg, is observed at 1.42 seconds after the launch to be at a height of 5.9 m and at a horizontal distance of 13.6 m from the launch point. Find...

Problem 2 (50 points) An object of mass m is launched from the ground at 30 degrees to the horizontal with an initial velocity v. After achieving a height of 10 m it begins to fall. Precisely at this point, it also explodes into two pieces of equal mass; these two pieces initially move horizontally. One of the pieces comes back and lands precisely where the object started out. (a) What was the y component of the initial velocity v?...

Motion in one dimension: In 2014, Orbital Sciences launched a private rocket into space to resupply the International Space Station. Unfortunately, because of Orbital Sciences’s decision to use 1960s era rocket engines that they purchased from an old Russian warehouse, the launch was a failure. If 95 seconds elapsed between the time the rocket was launched and the rocket hit the ground, calculate the maximum height of the rocket. Calculate the initial and final velocity of the rocket. While the...
