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.

12) A 2.0 kg firecracker that was initially sliding along the floor at 1.0 m/s (to the right) explodes with an internal energy of 10,000 J. If the firecracker breaks into two pieces that move in opposite directions, with the first piece having a mass of 0.75 kg and a speed of 30 m/s (to the right), then how much energy was converted into heat during the explosion? A) 0 kJ B) 1.5 kJ C) 2.7 kJ D) 4.3 kJ...

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?

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...

(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...
