a) conserving momentum
0 = 0.25m( 3vi +0.5vj) -0.25m(v) i +(0.5m)V3
V3 = -vi -vj
b)
third piece reaches ground first as its initial velocity is in downward direction
c)
center of mass always remains in tha same position

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...
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...

A projectile is launched at an initial velocity of 150i+200j m/s (vector) over a horizontal surface. The object’s mass is 120kg. At t=5.0s, the projectile explodes to 3 pieces: a 35 kg piece with a velocity of -15i+25j m/s, a 60 kg piece with a velocity of 80i m/s and a 25 kg piece with velocity 549i+685j m/s. a) determine the impulse that acted on the 35 kg piece during the explosion B) assuming that the average force on the...
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?...
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,...
Dr. C. #1: Exploding Projectile: A projectile of mass 9.6 kg is shot from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal. A. Assuming the ground underneath the projectile's path is flat, what is the maximum height h the projectile reaches, its horizontal range R, and the time it spends in the air? Suppose that, at the peak of the projectile's motion, an explosion splits the projectile in half and one...
A 215-kg projectile, fired with a speed of 123 m/s at a 61.0 ∘ angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally. A) Determine the magnitude of the velocity of the third fragment immediately after the...
