A 4.00-kg block of ice is placed against a horizontal spring that has force constant and is compressed 0.025 m. The spring is released and accelerates the block along a horizontal surface. You can ignore friction and the mass of the spring. (a) Cal-culate the work done on the block by the spring during the motion. We have a mass okay mass and it is being dropped onto a spring here is dropped onto a spring. Now let's label the information that we know as always, so mass is equal to two kilograms, two kilograms and it is dropped from a height of 40 centimeters. So the separation here stable, that h is equal to 40 centimeters. And we also know that this spring has a spring constant off 1960. If a spring is compressed (or stretched) a distance x from its normal length, then the spring acquires a potential energy Uspring(x): Uspring(x) = 1 2 kx2 (k = force constant of the spring) Worked Example A mass of 0.80 kg is given an initial velocity vi = 1.2 m/s to the right, and then collides with a spring of force constant k = 50 N/m. To summarise, the formation of pebbles, millimetre- to centimetre-sized agglomerates of microscopic dust and ice grains, can be understood with current For larger planetesimals, the porosity is expected to decrease with increasing depth due to lithostatic compression of the pebble structure [150]. know some properties of the spring. One key property is that if the length of the spring is shortened or lengthened by an amount Δl from its equilibrium value, the spring experiences a restoring force proportional to Δl. We call it a restoring force because it always acts in a direction to return the length of the spring to the equilibrium value. The energy stored in the spring will be equal to the difference in the potential energy at the two height of the spring (compressed and uncompressed), m g h i − m g h f = 1 / 2 k x 2 Furthermore, the compression of the spring would just be the difference in the h f − h i. This gives me two roots for compression, x = 0 And the second would be,. A block of mass m = 2.5 kg is dropped from height h = 40 cm onto a spring of spring constant k = 2000 N/m. Find the maximum distance the spring is compressed. (Use figure 8-36) The block initially has zero kinetic energy. It falls a distance h onto the spring, but, when it reaches the spring, it is moving at some speed, so it continues. 9 cm. this three mass system. XCM = YCM = Tries 0/10 Two Blocks and Compressed Spring Part A Two blocks with masses m1 = 1.1 kgand m2 = 3.8 kgare at rest on a frictionless surface with a compressed spring be-tween them. The spring is initially compressed by 57.0 cm and has negligible mass. When both blocks are released si-multaneously and the spring. Initially, block I (mass = 1.0 kg) and block II (mass = 2.0 kg) rest on a horizontal surface with block I in contact with the spring (but not compressing it) and with block II in contact with block I. Block I is then moved to the left, compressing the spring a distance of 50 cm and held in place while block II remains at rest. (Use g = 10 m/s 2. Q: A 500 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 300 N/m. The block becomes attached to the spring and compresses the spring 15 cm before momentarily stopping. While the spring is being compressed, what work is done on the block by (a) the gravitational force on it and (b) the spring force?.
