Explosion Problem:

A three-piece explosion A 10.0 g projectile is traveling east at 2.0 m/s when it suddenly explodes into three pieces. A 3.0 g fragment is shot due west at 10 m/s while another 3.0 g fragment travels 40◦ north of east at 12 m/s.

What are the speed and direction of the third fragment? Show and explain the steps for calculation.

    A missile is shot straight up into the air. At the peak of its trajectory, it breaks up into three pieces of equal mass, all of which move horizontally away from the point of the explosion. One piece travels in a horizontal direction of 35° east of north with a speed of 31 m/s. The second piece travels in a horizontal direction of 11° south of west with a speed of 7 m/s. What is the velocity of the remaining...

    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...

    Part 1:A 20.0 g ball of clay traveling east at 3.00 m/s collides with a 30.0 g ball of clay traveling north at 4.00 m/s. To find the total momentum of this system before the collision, we must determine the momentum of each piece of clay and then sum the two momenta vectorially. The 20.0 g piece has a momentum 0.06 kgm/s east, and the 30.0 g has a momentum 0.12 kgm/s north. What is the magnitude of the vector...
