A44.0-g block of ice at -15.0°c is dropped into a calorimeter (of negligible heat capacity) containing 100-g of water at 5.0°c. when equilibrium is reached, how much of the ice will have melted? the specific heat of ice is 2090 j/kg ∙ k, that of water is 4186 j/kg ∙ k, and the latent heat of fusion of water is 33.5 × 104 j/kg.

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
