please I have short time and I want only the answer without the solution QUESTION 4 A balance beam has a object of 51.1 g placed at a distance of 42. 4 cm to the right of the pivot When a second object is placed on the beam at a distance of 39 8 cm to the left of the pivot, the beam is in equilibrium. What is the mass of the second object, in units of grams?
QUESTION 7 A bullet of mass 40.0 g moving with a speed of 249 m/s strikes a block of wood of mass 2.00 kg and becomes imbedded in it (stuck inside it). The block had been originally at rest and is free to move. What is the speed of the block and bullet immediately after the collision, in units of m/s? QUESTION 10 If an object is initially at rest and then 'explodes' into two separate pieces, what do we...
1 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...

I need full answer. Dont forget the blanks. Q3: A bomb that is initially at rest at the origin explodes and breaks into two pieces of mass m 1454 kg and m2 2476 kg as shown in the figure below. If piece 1 has a velocity of +30 m/s directed along x, what is the velocity of piece 2 after the explosion? Answer: The system is made of and 21- v1f Total initial momentum is:
Question 19 This question contains multiple parts. Make sure to read all the instructions and answer each part. (408553) {2D Inelastic Collisions} At an Independence Day celebration show, a large firework is shot from the ground and, in the first stage of its bursting pattern, splits into two unequal parts. Part a (1 points) Assume that the firework has a mass of m0=0.30 kg and is launched from a cannon at an angle of θ0 =35.5 degrees with an...
please explain how you got your answers so I can understand The following relationships may be helpful. A spaceship of mass 4m kg moves in deep space along the x axis with an initial velocity 20i m/s and explodes in to two pieces of mass m kg and 3m kg as shown in the figure at right. Immediately after the explosion, the piece of mass m travels with a velocity 14 j m/s.

6. An explosion breaks an object initially at rest into two pieces, one of which has 3.0 times the mass of the other. If 7100 J of kinetic energy were released in the explosion, how much kinetic energy did the heavier piece acquire? Joules 7. A billiard ball is shot west at 2.20 m/s. A second, identical billiard ball is shot cast at 1.80 m/s. The balls has a glancing collision, not a head-on- collision, deflecting the second ball by...
