A projectile of mass 56kg is moving at constant speed of 8m/s when it explodes into three pieces A,B and C. A(20kg) flies on at 20m/s along the line of flight and B(16kg) flies at 15m/s at 450 to the line of flight in the forward direction. Find the velocity of mass C in magnitude and direction and estimate the energy supplied in the explosion

    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...

    An object with total mass mtotal = 6.4 kg is sitting at rest when it explodes into two pieces. The two pieces, after the explosion, have masses of m and 3m. During the explosion, the pieces are given a total energy of E = 45 J. What is the speed of the smaller piece after the collision? What is the speed of the larger piece after the collision? If the explosion lasted for a time t = 0.029 s, what...

    An object with total mass mtotal = 16.2 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.7 kg moves up and to the left at an angle of θ1 = 23° above the –x axis with a speed of v1 = 25.3 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right, an angle of θ2 = 28° to the right of the -y axis...

    a bullet of mass M is fired horizontally with speed 150 m/s î explodes into 3 pieces. One piece has mass M/4 and flies with speed 170 m/s î after explosion. Another piece has mass M/4 and flies with speed 20 m/s ĵ after explosion. You find two of the fragments and want to find the location of the third. In what direction and at what speed did the third fragment fly 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...
