In the figure below, block-2 of mass M = 1 Kg is at rest on a frictionless surface and touching the end of an un-stretched spring whose spring constant is 200 N/m. The other end of the spring is fixed to a wall. Block-1 of mass 2 Kg, travelling at speed v_1 = 4 m/s, collides with block-2 and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
A block with mass m = 14 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4174 N/m after being compressed a distance x1 = 0.512 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.7 m long. For this rough path, the coefficient of friction is μk = 0.44. 1) How much work is done by the spring as it accelerates...
A block with mass m = 16 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4850 N/m after being compressed a distance x1 = 0.51 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.5 m long. For this rough path, the coefficient of friction is μk = 0.45. How much work is done by the spring as it accelerates the...
A block with mass m = 16 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 5072 N/m after being compressed a distance x1 = 0.568 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.8 m long. For this rough path, the coefficient of friction is μk = 0.48. 1) How much work is done by the spring as it accelerates...
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...
A mass of 1 kg and initial speed 10 m/s slides across a horizontal frictionless surface and hits a spring of force constant 200 N/m. How much will the spring be compressed from its relaxed length when the block will be at rest momentarily?
A projectile of mass m is shot into a block of mass M. The block is initially at rest at the edge of a frictionless table. The table top is a height h above the floor. The projectile hits and sticks to the block. After impact the masses land a distance d from the edge of the table. Determine the expression for the initial speed of the projectile.
A solid block of mass m2 = 2.3 kg, at rest on a horizontal frictionless surface, is connected to a relaxed spring (with spring constant k = 260 N/m whose other end is fixed. Another solid block of mass m1 = 2.2 kg and speed v1 = 3.3 m/s collides with the 2.30 kg block. If the blocks stick together, what is their speed immediately after the collision?What is the maximum compression of the spring?
A block with mass m = 1.86 kg
is placed against a spring on a frictionless incline with angle θ =
33.9° (see the figure). (The block is not attached to the spring.)
The spring, with spring constant k = 25 N/cm, is compressed 28.1 cm
and then released. (a) What is the elastic potential energy of the
compressed spring? (b) What is the change in the gravitational
potential energy of the block-Earth system as the block moves from
the...
3. A block of mass M oscillates with amplitude A on a frictionless horizontal table, connected to an ideal spring of force constant k. The period of its oscillations is T. At the moment when the block is at position x-A and moving to the right, a ball of clay of mass m dropped from above lands on the block : k (a)What is the velocity of the block just before the clay hits? b) What is the velocity of...
