Determine the initial speed of the block

Reference no: EM13249344

a frictionless inclined plane of angle 20 has a spring force constant k= 500 N/m fastened securely at the bottom so that the spring is parallel to the surface. a block of mass 2.5 kg is placed at a distance d=0.300 m from the spring. from this posistion the block is projected toward the spring with a speed v. the spring is compressed by 0.131 m from its equilibrium position when the block momentarily comes to rest.

a.) what is the work done by the force of gravity on the block during this period?

b.) what is the work done by the spring force in this period?

c.) determine the initial speed v of the block?
