    Thermodynamics question regarding latent heat of fusion of ice.

    Q = mL for state changes. (mass, L being the heat needed, which is what you're trying to find) and for heating of liquids, Q = mC * change in temp heat lost by copper = -heat lost by water (i.e. heat is gained by water) mC * change in temp for copper = - (mL + mC * change in temp for water)...

    Finding the acceleration when initial velocity is not known.

    Homework Statement In 2.0 s, a particle moving with constant acceleration along the x-axis goes from x = 10 m to x = 50 m. The velocity at the end of this time interval is 10 m/s. What is the acceleration of the particle? Homework Equations kinematic equations The Attempt at a...
