really need help. please. A 4.5 kg object moving in the +x direction at 5.5 m/s...
A 19.5kg object moving in the +x direction at 5.5 m/s collides head on with a 15.9kg object moving in the -x direction at 3.5m/s. Part A Find the final velocity of each mass if the objects stick together. Part B Find the final velocity of each mass if the collision is elastic. Part C Find the final velocity of each mass if the 19.5 kg object is at rest after the collision. Part D Is the result in part...
A mass of 5 kg is moving at 8.2 m/s in the positive x direction and collides in a perfectly elastic collision with a second mass which is not at rest. After the collision, the second mass is moving at 12.3 m/s in the +x direction. If the 5 kg mass stops after the collision, what is the amount of the second mass in kg?
A mass of 6 kg is moving at 9.1 m/s in the positive x direction and collides in a perfectly elastic collision with a second mass which is not at rest. After the collision, the second mass is moving at 12.2 m/s in the +x direction. If the 6 kg mass stops after the collision, what is the amount of the second mass in kg?
A 3.0-kg object moving 8.0 m/s in the positive x direction has a one-dimensional elastic collision with an object (mass = M) initially at rest. After the collision, the object of unknown mass has a velocity of 6.0 m/s in the positive x direction. What is M? a. 6.0 kg b.5.0 kg c. 4.2 kg d. 7.5 kg e. 8.0 kg
11. A 0.10 kg object with a velocity of 2.0 m/s in the +x direction makes a head-on elastic collision with a 0.15 k? object moving in the -x direction with a velocity of 3.0 s. What is the final velocity of the 0.10 kg object after the collision? A- 4.0 m/s
A 4.0 kg object is moving at 5.0 m/s NORTH. It strikes a 6.0 kg object at rest. The objects have an elastic collision and move in the NORTH or SOUTH direction. The velocity of the 6.0 kg object after the collision is
A ball of mass 0.442 kg moving east (+x direction) with a speed of 3.72 m/s collides head-on with a 0.221 kg ball at rest. Assume that the collision is perfectly elastic. a) What is be the speed of the 0.442-kg ball after the collision? b) What is be the direction of the velocity of the 0.442-kg ball after the collision? to the east or to the west c)What is the speed of the 0.221-kg ball after the collision? d)What...
A mass is moving at 8 m/s in the +x direction and it collides in a perfectly elastic collision with a mass of 3 kg moving in the -x direction. The collision takes places in 0.21 seconds and after the collision the mass that was moving in the +x direction is moving in the -x direction at 9 m/s and the mass that was moving in the -x direction is moving in the +x direction at 11 m/s. What is...
