• Compressed Springs and Conservation of Momentum

  The spring generates a force of this magnitude at each end of the spring, so if we take a spring of equilibrium length x,the force acting on each mass is +kdx and -kdx (so that there is no net force and the system is in equilibrium) b)The energy

• Bullet collides with mass connected to a spring

  total momentum the system comprising of the bullet and the two masses A and B, connected by the spring, is conserved.

• Two Body system: Motion of two masses attached by spring

  m2 and will be maximum when both will move with the velocity of center of mass of the system thus the maximum extension in the spring can be calculated by conservation of energy of oscillation (relative to center of mass) as Loss in energy = gain in

• sample exam questions (please do in word): A block of mass 2.5 kg is placed against a compressed spring (k = 2900 N/m) at the bottom of an inclined plane, as shown

  Hence according to law of conservation of energy we can write Gain in gravitational potential energy = loss in elastic potential energy Now say the maximum distance covered be l, initial compression in the spring be  l (= 0.14 m) and the angle of

• Speed of Blocks on an Incline

  The spring is unstretched, when both masses are in their equilibrium positions. The surface of the incline is frictionless. The block atop the spring is a distance h above the horizontal surface when the spring is unstressed.

• Conservation of momentum.

  356017 Conservation of linear momentum. A compressed spring is placed with a light adhesive between the large car and the small car such that it is touching the facing ends.

• spring costant

  The acceleration of gravity is 9.8 m/s2. Calculate the spring force costant k. Answer in units of N/m We can solve this problem using conservation of energy.

• Find amplitude based on the conservation of total energy

  m = 0.5kg k = 20 N/m v = 1.5m/s At equilibrium pt the spring is not stretched or compressed, hence the entire energy in the system is in the form of kinetic energy of the mass.

• Combining Conservation Laws

  block stops, its final kinetic energy is zero and conservation of energy requires that the block's initial kinetic energy will be completely converted to the elastic energy stored in the spring.
