A 98 kg block is at rest on a horizontal frictionless surface and is attached to one end of a horizontal spring. The other end of the spring is attached to the wall. A 2kg block traveling horizontally at 10m/s strikes the 98kg block and sticks to it. After the collision the maximum elastic potential energy stored in the spring is ????

A horizontal spring attached to a wall has a force constant of k=850 n/m. A block of mass m=1.0 kg is attached to the spring and rests on a frictionless, horizontal surface.

The block is pulled to a position x_i=6.0 cm from equilibrium and released. Find the elastic potential energy stored in the spring when the block is 6.0 cm from equilibrium and when the block passes through equilibrium.

A 8.80 10-3 kg bullet is fired horizontally into a 2.37 kg woodenblock attached to one end of a massless, horizontal spring (k = 855N/m). The other end of the spring is fixed in place, and the springis unstrained initially. The block rests on a horizontal,frictionless surface. The bullet strikes the block perpendicularlyand quickly comes to a halt with in it. As a result of thiscompletely inelastic collision, the spring is compressed along itsaxis and causes the block/bullet to oscillate with an amplitude of0.200 m. What is the speed of the bullet?

<p>A 0.0303-kg bullet is fired horizontally into a 3.13-kg wooden block attached to one end of a massless, horizontal spring (k = 871 N/m). The other end of the spring is fixed in place, and the spring is unstrained initially. The block rests on a horizontal, frictionless surface. The bullet strikes the block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the block/bullet to oscillate with an amplitude of 0.280 m. What is the speed of the bullet?<br /><br /></p>
