  1. A spring stretches 5 cm when a force of 2.0 N is applied to it. What is its spring constant?

  1. What is the elastic energy stored in the spring when compressed 5 cm?

  1. If the stored spring elastic energy is applied to a cart (mass= 2.0 kg) on a frictionless track, what would be the cart’s velocity?

A 2.70 kg mass is pushed against a horizontal spring of force constant 28.0 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way. When the spring has been compressed enough to store 10.0 J of potential energy in it, the mass is suddenly released from rest. What is the greatest acceleration of the mass? Express your answer with the appropriate units.

A spring is mounted horizontally as shown to the right. A crate, which has a mass of 8.5 kg is pressed against the spring with a force of 350 N. As a result the spring is compressed a distance of 82.0 cm. The mass is then released and is allowed to slide along the horizontal, frictionless surface. a. What is the spring constant of this spring? b. How much elastic potential energy will be stored in the spring? c. How...

In a spring gun system, a spring with a spring force constant 370 N/m  , is compressed 0.13 m . When fired, 79.1% of the elastic potential energy stored in the spring is eventually converted into kinetic energy of a 5.50×10−2 kg uniform ball that is rolling without slipping at the base of a ramp. The ball continues to roll without slipping up the ramp with 90.3 % of the kinetic energy at the bottom converted into an increase in gravitational...

A horizontal spring attached to a wall has a force constant of 760 N/m. A block of mass 1.30 kg is attached to the spring and oscillates freely on a horizontal, frictionless surface as in the figure below. The initial goal of this problem is to find the velocity at the equilibrium point after the block is released. (c) Find the energy stored in the spring when the mass is stretched 5.80 cm from equilibrium and again when the mass...
