A(n) 22 kg object, initially at rest in free space, “explodes” into three segments. The masses of two of these segments are both 7 kg and their velocities are 2.8 m/s. The angle between the direction of motion of these segments is 62 ◦ . What is the speed of the third segment? Answer in units of m/s.

object initially at rest explodes into three picces. Piece A has a mass of 5 kg, B has a mass of 3.0 kg, and C has a mass of 2.5 kg. After the explosion, A's velocity is (3.0 m/s)i + (2.0 m/s) j and B's velocity is (2.0 m/s)i - (3.0 m/s) j y at rest explodes into three pieces. Piece A has a mass of 5.0 a. What is C's velocity after the explosion? b. Calculate the change...
An object with total mass mtotal = 16.1 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.6 kg moves up and to the left at an angle of θ1 = 22° above the –x axis with a speed of v1 = 25 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right an angle of θ2 = 27° to the right of the -y axis...
An object at rest explodes into three fragments. The figure shows
the momentum vectors of two of the fragments.
What is p_x of the third fragment?
What is p_y of the third fragment?
answer in "kg m/s" please!
"HINT" the answer IS NOT p3_x=0 & p3_y=-2
A 10kg mass initially at rest explodes into three pieces. A 4.5kg piece goes north at 20 m/s and a 2.0kg piece moves eastward at 60 m.s. what is the speed of the third piece? a. 80.0 m/s b. 25.7 m/s c. 42.9 m/s d. 60.0 m/s e. 34.3 m/s
025 (part 1 of 4) 10.0 points A man pushes a 24 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually in- creases his force so that the force he exerts on the box varies in time as F (7.7 N/s) t. Af- ter 4 s, he stops pushing the box. The force is always exerted in the same direction. What is the velocity of the box after...
The object shown is initially at rest. At t = 0 the object explodes into 3 pieces of equal mass as shown. The angles are 0 = 29° and 0 = 38°. Take upward and rightward as the positive directions. Part 1: Find the velocity components of the piece on the right. Vx= Vy= Part 2: If the explosion lasted for 0.01 seconds, what is the average force experienced by the piece on the right? Take the mass to be...
A 10kg mass initially at rest explodes into three pieces. A 4.5kg piece goes north at 20 m/s and a 2.0kg piece moves eastward at 60 m.s. A) Determine the magnitude and direction of the velocity of the third piece. B) Compare the final Kinetic Energy of the system to the original kinetic energy of the system.
