Find (a) the kinetic energy, (b) the magnitude of the momentum for object A and (c) the kinetic energy, (d) the magnitude of the momentum for object B. Object A Object B Mass 2.20 kg 5.70 kg Speed 5.70m/s 2.20m/s A 2.20 kg 5.70 kg 5.70 m/s 2.20m/s

Could someone explain finding the fraction of momentum and kinetic energy lost please? The mass of cart A is 0.508 kg and the mass of cart B is 1.011 kg.

A 1960 kg truck traveling north at 30 km/h turns east and accelerates to 54 km/h. (a) What is the change in the truck's kinetic energy? (b) What is the magnitude of the change in its momentum?

Beatrice stands at rest on her skateboard. The mass of Beatrice and the skateboard together is 75 kg. Isaac Newton throws a 3.0 kg ball horizontally to the right at 4.0 m/s to Beatrice, who catches it.  (a)  What is the final speed of Beatrice and the skateboard? (b)  How much mechanical energy was lost in the process?

A spring pushes against two horizontal carts that are held together by a thread on a frictionless surface. Cart A is 1.5-kg and Cart B is 4.5-kg. The thread is then burned, releasing the stored energy of the spring and the carts move away from each other. The Cart A moves with a velocity of 27cm / s to the left. What is the velocity of the Cart B, in cm / s ?

You and another astronaut are in space.  You throw a tool to them that has a mass of 17kg.  Your mass is 87kg and the other astronaut's mass is 91kg. Initially you and the other astronaut are at rest.  You threw the tool at a speed of 7m/s.  What is the velocity of the astronaut after they catch the tool?

A Vulcan spaceship has a mass of 6.50 × 104 kg and a Romulan spaceship is twice as massive. Both have engines that generate the same total force of 9.50 × 106 N. If each spaceship fires its engine for the same amount of time, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the energy of the Vulcan spaceship if the engines are fired for 102 s.

An object is traveling such that it has a momentum of magnitude 21.9 kg m/s and a kinetic energy of 300 J. Determine the following. (a) speed of the object in meters per second m/s (b) mass of the object in kilograms kg

The ballistic pendulum is a device to measure the speed of a bullet using conservation of energy and momentum. A 20 g bullet is fired horizontally into a 1.1 kg wood block hanging from a 1.2-m-long string. The bullet embeds itself into the block, and the block then swings out to an angle of 35°. A. How high does the block of wood go relative to its initial height when its hanging straight down? B. What is the increase in gravitational potential energy of the wood block at its maximum height? C. Use conservation of energy to determine the speed of the block just after the bullet strikes it. D. Use conservation of momentum to determine the speed of the bullet right before it strikes the block.
