what action on our part is neccesary to make the dryiceblock move faster and faster,that is accelerate continuosly?if you are speeding it up, how must you move?

A 1.0 kg metal head of a geology hammer strikes a solid rock with a velocity of 5.0 m/s. Assuming all the energy is retained by the hammer head, and that it's heat capacity is 0.11 cal/(gC), how much will its temperature increase?

suppose the dry ice block is moving to begin with and we exert a steady force,either speeding up or slowing down.how does the block behave? now suppose we make the steady force smaller and smaller.how does the dryice block behave? how will it behave when the force we are ...
