Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass m3 = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.

1. In an experiment, you throw a rubber ball of mass m = 25.0 g onto a block of mass M = 250 g that is initially at rest at the edge of a table of height h = 0.98 m. (Figure) The ball bounces back with a speed of 1.01 m/s, and the block eventually lands at d = 1.02 m from the bottom of the table. What is the speed of the ball, right before it hits the block?

Problem 3: An egg with a mass m is dropped from rest from a height h and falls to the ground and breaks. Part (a) Write an expression for the magnitude of the net impulse imparted to the egg as it is stopped by the floor. Your expression will be in terms of m, h, and g. Neglect air resistance. Expression : J = Select from the variables below to write your expression. Note that all variables may not be required.

O A 1,300-kg car is traveling at a speed of 10 m/s with respect to the ground when the driver accelerates to make a green light. The momentum of the car increases by 12,800 kg m/s. Draw a sketch showing the initial and final states of this scenario. List all the quantities you can determine using this information and determine three of those quantities.

Quesitos: The drawing shows a bullet passing through two blocks that rest on a horizontal, frictionless surface. Rule out air resistance. The bullet completely passes through the first block and is buried in the second block. Notice that after the collision, both blocks move. Can the Conservation Principle be applied from Linear Momentum to this three-body system? Justify your answer (Ignore any loss of mass from the first block). Problem: A 4.00-g bullet moves horizontally with velocity of + 355m / s. The mass of the first block is 1150 g, and its velocity after the bullet passes through it it is +0.550 m / s. The mass of the second block is 1530 g. (a) Obtain the speed of the bullet after passing through the first block, (b) obtain the velocity of the second block after the bullet is buried in it

How do I solve this problem step by step?

Three carts are moving on a frictionless horizontal track as shown in the figure.  The 4.00 kg cart is moving to the right with a speed of 7.0 m/s, the 10.0 kg cart is also moving to the right with a speed of 6.0 m/s while the 3.00 kg cart moves to the left with a speed of 7 m/s.  Find the final speed of the carts when they are all stuck together.   Hint:  The order at which the carts stick together does not matter.  Can you see why?

A package of mass mm is released from rest at a warehouse loading dock and slides down the hhh = 3.4 mm - high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m2m, from the bottom of the chute.   Suppose the packages stick together. What is their common speed after the collision?  I got the answer to be 2.7 m/s which is correct.   Suppose the collision between the packages is perfectly elastic. To what height does the package of mass mm rebound?

() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg. Before the collision, blocks mą and mg are stationary and the spring is relaxed. m2 Frictionless - For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move) • For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any force acts on mg and cause it to move)…

Problem: You are lead engineer on the design of a crash test apparatus that verifies collisions of varying types. A m = 2 kg mass, when suspended above from a light-weight wire of L = 1.5 m, is first released at an angle of 90°, and correspondingly a height h = L. The tethered ball swings toward the waiting block of M = 4 kg. collides, then rebounds back to an angle of 0 = 32°. In this case, the collision between m and M is elastic, which prompts M's rightwards motion a distance of Ax = 2.1 m, from which the coefficient of kinetic friction between the block and surface on which it is slid is determined. m L h 0 M
