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?...

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 rocket shot at 22m/s at 75 degrees above the horizontal explodes into four equal pieces at the highest point of its trajectory. One piece moves horizontally at 2m/s, a second one moves vertically upward at 3m/s and a third moves at 1.5 m/s vertically downward. What is the velocity of the fourth piece?

A metal gas storage tank explodes breaking into three pieces, two of equal mass and the third twice the mass of each of the others. The two equal mass parts fly off at speeds of 21.0 m/s at an angle of 100º between them. what's the speed of the heavier piece?

(3) A particle of mass 3 kg travels along the y-axis with a speed of 5 m/s. Then the particle explodes into two pieces. One piece moves as: m = 2 kg = 3i+2j m/s (a) Find the velocity (vector) of the other piece. (b) Find the impulse, J (a vector), on the 2 kg piece. (c) Find the impulse, J (a vector), on the other piece. (d) Considering the energy, what can you say about the explosion?

1- A block slides along a frictionless surface at 2.4 m/s. A second 3.5-kg block, sliding at a faster 7.5 m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is 4.6 m/s. What was the mass of the first block? 2-A 15 g ball of clay traveling west at 4 m/s collides with a 50 g ball of clay traveling 30° north of east at 3.5 m/s. What is the speed...

10.9 A radioactive nucleus (mass = 1.70*10-26 kg) is at rest. It suddenly decays (explodes) into three pieces. One piece has mass mi = 5.00*10-27 kg and is found to be moving along the +y axis with a speed of 6.00* 10 m/s. A second piece with mass m2 = 8.40*10-27 kg moves along the +x axis with a speed of 4.00* 10° m/s. Assuming the mass is held constant, find the velocity of the third and final piece that...

17. A dinner plate falls vertically to the floor and breaks up into three pieces, which slide horizontally along the floor. Immediately after the impact, a 320-g piece moves along the +X-axis with a speed of 2.00 m/s and a 355-g piece moves along the +y-axis with a speed of 1.50 m/s. The third piece has a mass of 100 g. In what direction relative to the +x-axis does the third piece move? (a) 39.8º from the +x-axis (b) 36.9°...
