Calculate the weight of the ice block.
As the block of ice falls, the air resistance force $F$ acting on it changes. State the value of $F$ at time $t=0$.
State the value of $F$ when $t=10.0\,\text{s}$.
Explain why the force $F$ changes.
State the energy change that occurs when the block is falling at terminal velocity.
Using information from Fig. 9.2, determine the greatest kinetic energy of the block when it is falling to the ground at terminal velocity.
The block hits the ground and comes to rest. This impact makes some of the ice melt. The specific latent heat of fusion of ice is $330\,\text{J g}^{-1}$. Calculate the largest possible mass of ice that melts as a result of the impact.
In reality, the mass of ice that melts on impact is smaller than the amount found in (c)(i). Suggest two reasons for this.
As the solid ice melts, it becomes liquid water. Describe, in terms of molecules, how ice is different from liquid water.
