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
really need help. please. A 4.5 kg object moving in the +x direction at 5.5 m/s collides head-on with a 2.5 kg object moving in the -x direction at 4.0 m/s. Find the final velocity of each mass for each of the following situations. (Take the positive direction to be +x.) (a) The bodies stick together 4.92 X m/s (4.5 kg mass) m/s (2.5 kg mass) (b) The collision is elastic. 4.92 5.92 m/s (4.5 kg mass) m/s (2.5 kg...
A 3.24 kg object initially moving in the positive x-direction with a velocity of +5.15 m/s collides with and sticks to a 1.66 kg object initially moving in the negative y-direction with a velocity of -2.54 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.) Vfx = ? Vfy = ?
A 2-kg block moving in the positive x direction with a speed of 5.0 m/s collides with a 3-kg block moving in the same direction with a speed of 2.0 m/s. After the collision the 3-kg block moves at 4.2 m/s. Find the velocity of the 2-kg block after the collision. Is the collision elastic or inelastic? Justify your answer.
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 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...
An 4.7-kg object moving at 12.2 m/s catches up and collides with an 22.3-kg object moving at 2.1 m/s in the same direction. After the collision the 4.7-kg object is observed to be moving in the opposite direction with the speed of 2.6 m/s. How much kinetic energy was lost in this system?
An object (A) of mass m A = 29.0 kg is moving in a direction that makes angle of 40° north of east with a speed v A = 5.10 m/s, while object (B) of mass m B = 17.5 kg is moving due north with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. An...
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...
