Block A of a mass 0.7 kg is sliding to the right at a speed of 4.7 m/s while block B of mass 4.5kg is sliding to the right with a velocity of 1.2 m/s. The surface is frictionless for both blocks. If they collide perfectly elastically what is the speed of block A after the collision?
Two blocks are sliding across a horizontal frictionless tabletop. Block A has a mass of 5 kg, and it is sliding directly southward with a speed of 8 m/s. Block B has a mass of 7 kg, and it is sliding directly westward with a speed of 4 m/s. The blocks then collide and stick together. What is the speed of the new combined block after the collision?
Particle A is at rest, and particle B collides head-on with it. The collision is completely inelastic, so the two particles stick together after the collision and move off with a common velocity. The masses of the particles are different, and no external forces act on them. The de Broglie wavelength of particle B before the collision is 1.8 × 10-34 m. What is the de Broglie wavelength of the object that moves off after the collision?

Consider two masses sliding across a frictionless surface about to undergo a head-on collision as shown in the figure. The first mass (m1 =3 kg) is travelling to the right with a speed of v1 = 8 m/s. The speed of the second mass (m2 = 5 kg) is unknown. After the masses collide, ma rebounds moving off at a speed of v = 2 m/s in the opposite direction, while mz is motionless. a)(10 pts.)

A mass m1 moving at a velocity of v1 collides elastically with a mass m2 which is initially at rest. a. what fraction of the original kinetic energy does mass 1 retain after the collision? Give your answer in terms of the masses. (Hint: Find the ratio of Kafter/Kbefore for the first mass) b. a mass m1 is placed on a frictionless ramp at a height of h. It is then released and slides down without rolling to elastically collide...
1- A ball with mass M, moving horizontally at 2.8 m/s, collides elastically with a block with mass 3.6M that is initially hanging at rest from the ceiling on the end of a 58-cm wire. Find the maximum angle through which the block swings after it is hit, in degrees. 2- A 0.15 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.72 m/s. It has a head-on collision with a 0.30...
6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...
