84.. An ideal spring is used to stop blocks as they slide along a table without friction (Eigure 6-42). A 0.85-kg block traveling at a speed of 2.1 m/s can be stopped over a distance of o.15 m, once it makes contact with the spring. What distance would a 1.3- kg block travel after making contact with the spring, if the block were traveling at a speed of 3.3 m/s?

3. A wooden block with mass 500g is pushed along a table to give it an initial speed of 3.00 m/s. It moves down the table and comes into contact with a spring, which it compresses. The block then comes to a stop. The block moves a distance of 1.20m between when the pushing force stops and when it is stopped by the spring. The coefficient of kinetic friction between the block and table is 0.150. The spring has a...

5. Blocks of mass m and 2m are free to slide without friction on a horizontal wire. They are connected by a massless spring of equilibrium length L and force constant k. A projectile of mass m is fired with velocity v into the block with mass m and sticks to it. If the blocks are initially at rest, what is the maximum displacement between them in the subsequent motion? E E 2m

Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...

Block 2 (mass 1.10 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 144 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.70 kg), traveling at speed v1 = 3.60 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed? Answer 0.305 m My question is how did they solve...

1. In the figure, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 2.2 kg, encounters a coefficient of kinetic friction μL = 0.40 and slides to a stop in distance dL = 0.15 m. Piece R encounters a coefficient of kinetic friction μR = 0.50 and slides to a stop in distance dR = 0.36 m. What...

Blocks A and B are released from rest when the spring is unstretched. Blocks A and B have masses ma = 2 kg and mp = 3 kg and the linear spring has stiffness k = 7 N/m. If all sources of friction are negligible, determine the velocity of block A after block Bhas dropped 2.2 m downward. Assuming that A never leaves the horizontal surface shown and the cord connecting A and B is inextensible. The answer needs to...
