Momentum Conservation and Collisions Lab Report #3

Macmillan Learning Two particles approach each other with equal and opposite speed, v. The mass of one particle is m, and the mass of the other particle is nm, where n is just a constant factor. Snapshots of the system before, during, and after the elastic collision are shown. m Before nm What is the value of n Collision V m,final m n = After V nm After the collision, the first particle moves in the exact opposite direction with speed 2.95v, and the speed of the second particle, Unm,final, is unknown. nm,final

Question Number: 93 Question Id: 7005954973 Is Question Mandatory : No Calculator : None Response Time: N.A Think Time: N.A Minimum Instruction Time: 0 A ball of mass 2m and a system of two balls with equal masses m connected by a massless spring, are placed on a smooth horizontal surface (see figure below). Initially, the ball of mass 2m moves along the line passing through the centres of all the balls and the spring, whereas the system of two balls is at rest. 2m m m Assuming that the collision between the individual balls is perfectly elastic, the ratio of vibrational energy stored in the system of two connected balls to the initial kinetic energy of the ball of mass 2m is A) 1 B WINN

Help with this homework question would be great, thanks!

Current Attempt in Progress Ion Thrusters III: Current and Power. You and your team are designing a new propulsion engine that ejects xenon (Xe) ions in one direction, causing a spacecraft to accelerate in the opposite direction, in accordance with the conservation of linear momentum and the impulse-momentum theorem. This is exactly what happens when a rocket engine expels high velocity particles when burning fuel, except that, in the case of the ion drive, the ions are accelerated with an electric field. In this process, Xe gas atoms are ionized so that they each acquire a net charge of +e. They are then subjected to an electric field, which accelerates and ejects the ions from the engine. In the thruster you are designing, the Xe atoms accelerate through a potential difference of 2.06 kV between a grounded electrode and a negatively charged grid, through which the ions are ejected at a speed of 55.0 km/s relative to the engine. (a) If Xe ions are ejected from the thruster at a rate…

please help me with this problem. Given: A ball of clay mass M/8 A larger mass as known as Mis attached to a spring with spring constant k. A ball of clay mass "M/8" moves with speed "v" towards a larger mass M. As the a ball of clay hit and sticks on the a larger mass who was initially still. a) What would be the speed of the combination after the collision? b) How much did the spring compressed c) How long did it take for the spring to be compressed due to the collision? K M/8 M

Block A with a mass of 2kg is moving to the right at 5m/s. It collides with block B with a mass of 3kg moving at 1m/s to the left. A. What is the total momentum before collision? magnitude: direction: B. What is the total momentum after collision? magnitude: direction: C. If collision is perfectly inelastic, what is their velocity after collision? magnitude: direction: D. If block A stops moving, what is the velocity of block B? magnitude: direction: E. What is the coefficient of restitution if block A stops moving after collision with block B?

1. Consider a bomb of mass M (see figure below) that sits in the middle of space. Initially, the bomb is at rest. What is the initial momentum [kg∙m∙s-1] of the bomb? 2. Consider the same bomb as before, but now after it explodes. Using the figure below and what we know about conservation of momentum, what will the total momentum [kg∙m∙s-1] of the system after the explosion?

Part II. Elastic vs Perfectly Inelastic Collision 1. Compare the total momentum before and total momentum after of elastic and perfectly inelastic collision. 2. Compare the total KE before and total KE after of elastic and perfectly inelastic collision. 3. If the velocity ofa moving body is doubled, what does this do to kinetic energy and momentum of the body? 4. A 25g ball slides down a smooth inclined plane 0.850 m high that makes an angle of 35 degrees with the horizontal. The ball slides down into an open box of 150 g mass. The ball and the box slide off the end of a table 1.0 m high. a.) How far from the base of the table will the box and ball hit the ground? b.) What is their final velocity? 0.M50 m

True or False? 1. You can change an object's momentum without changing its mass or velocity 2.The coefficient of restitution be negative. 3.When the coefficient of restitution is equals 0, it means that the objects stick together after collision. 4.When the coefficient of restitution is equals 0, it means that the objects stick together after collision.

3 Momentum In 1977 the planet Alderaan, with a mass of 3 × 1024 kg, exploded. Assume it was initially at rest and experienced no external interactions. Problem 3.1. If the planet blew apart into two pieces with 40% of its mass flying away in one piece at 4,000 km/s, what speed did the rest of the planet have relative to its original frame? Problem 3.2. Consider instead that the planet instead blew apart into three pieces, with 30% of its mass flying away at 3, 000 km/s, and 20% of its mass flying away at 5, 000 km/s at an angle of 120o relative to the velocity direction of the first fragment. Draw a diagram of this situation. What velocity did the rest of the planet have? Report the direction by specifying its angle relative to the velocity direction of the first fragment.
