. Two masses travel toward each other across a horizontal, frictionless surface. They collide, resulting in 100 Joules of kinetic energy being lost. Below is a list of the known quantities. Mass#1 = 5.00 kg and has an initial velocity of 10.0 m/s to the right and a final velocity of 3.00 m/s to the right. Mass#2 = unknown and has an initial velocity of 4.00 m/s to the left and a final velocity that is unknown. What is the mass and final velocity of Mass#2?

Expert Solution

(negative sign indicates the direction of motion of m2 initially is towards left)

Conserving momentum of two masses before and after collsion,

------(1)

Loss in kinetic energy of system ,

----(2)

Dividing (2) by (1)

Substituting above value in (1)

Unknown mass and its final velocity towards right.

Two masses are on a horizontal, frictionless surface. The plane of the surface is the x-y plane. Mass m1 = 1.0kg is at rest while mass m2 = 2.0kg is moving in the positive x-direction at 15m/s. The two masses then undergo a collision and mass m2 is moving with a speed of 9.0m/s at an angle of 35 degrees after the collision. 1) What is the speed of the center of mass of the two masses before the collision?...

Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them as shown in the figure below. A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of v with arrow3m = 1.70 m/s. (a) What is the velocity of the block...

Two objects of masses m and 8m are moving toward each other along the x-axis with the same initial speed v0 = 525 m/s. The object with mass m is traveling to the left, and the object with mass 8m is traveling to the right. They undergo an elastic glancing collision such that m is moving downward after the collision at a right angle from its initial direction. What is the final speeds of the two objects m and 8m?...

Two trains (on separate tracks) travel toward each other, the first at 60.0 km/s and the second at 40.0 km/s. Both turn on their whistle, the first one emitting a frequency of 200 Hz and the second one emitting a frequency of 220 Hz. What frequencies do they each receive if the speed of sound in air is 330 m/s? Hint: Draw a diagram or do this one in steps. Is the source or the observer moving?

If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it oscillates. Suppose it is displaced 0.125 m from its equilibrium position and released with zero initial speed. After 0.860 s, its displacement is found to be 0.125 m on the opposite side and it has passed the equilibrium position once during this interval.Find the amplitude of the motion.=________________mFind the period of the motion.=________________sFind the frequency of the motion.=_________________Hz

Two boys are sliding toward each other on a frictionless, ice-covered parking lot. Jacob, mass 45 kg, is gliding to the right at 7.95 m/s, and Ethan, mass 31.0 kg, is gliding to the left at 10.9 m/s along the same line. When they meet, they grab each other and hang on. (a) What is their velocity immediately thereafter? magnitude m/s direction (b) What fraction of their original kinetic energy is still mechanical energy after their collision? % (c) That...
