A child hits an ice cube with a mass of 10 grams on a table with a force of 10 N. The impact lasts 0.02 seconds. The ice cube flies off the table, which is 1 meter high and lands some distance away. Assume there is no friction between the ice cube and the table. a. What is the velocity of the ice cube when it leaves the table? b. What is the final velocity of the ice cube just before it hits the floor? c. What is the momentum of the ice cube just before it hits the floor? d. What distance will the ice cube land from the foot of the table? e. Suppose the ice cube had broken into two pieces just after the child hit the ice and moved away from each other while falling to the floor. How would the total momentum of the two pieces just before they hit the floor compared to the momentum you found in part (c)?

A child hits an ice cube with a mass of 10 grams on a table with
a force of 10 N. The impact lasts 0.02 seconds. The ice cube flies
off the table, which is 1 meter high and lands some distance away.
Assume there is no friction between the ice cube and the table.

How many US pennies (mass 2.5 grams) can you stack on an ice
cube having a mass of 4.20 kg floating in water, before it starts
to sink? (let the density of the water be 1000 kg/m3 and the ice
cube be 917 kg/m3)

An ice cube with a mass of 0.0750kg is taken from a freezer,
where the cube’s temperature was -10.0∞C, and dropped into a glass
of water at 0.00∞C.
a) If no heat is gained or lost from outside, how much water
will freeze onto the cube?
b) Is it possible to add so much ice to the glass that all the
water freezes? Explain.

1) An ice cube of mass m at 0 ?C is placed in a large 20 ?C
room. Heat flows (from the room to the ice cube) such that the ice
cube melts and the liquid water warms to 20 ?C. The room is so
large that its temperature remains nearly 20 ?C at all times.
Calculate the change in entropy for the (water + room) system due
to this process. Assume that m is in kg.

a) An ice cube initially at zero degrees C has mass 37g. It is
used to cool a hot cup of water at 184 which has mass 200g. What is
the final temperature in degrees Celcius? Use as specific heat of
water 4.18 kJ/(kg K) and the heat of fusion 334 kJ/kg.
b) A mass of 1kg is attached to a spring with spring constant
10N/m. How many meters down does its equilibrium position fall when
it is used to...

An ice cube whose mass is 50 g is taken from a freezer at a
temperature of -10C and then dropped into a cup of water at 0C. If
no heat is gained or lost from the outside, how much water will
freeze onto the cup?
An ice cube of mass 0.029 kg and temperature -13 ∘C is dropped into a styrofoam...
An ice cube of mass 0.029 kg and temperature -13 ∘C is dropped
into a styrofoam cup containing water of mass 0.4 kg and
temperature 20 ∘C. Calculate the final temperature in degrees
celcius and give your answer to one decimal place. (For simplicity,
we ignore here the temperature change of the cup.)
The specific heat of ice is 2200 J/kg ∘C and the specific heat
of water is 4186 J/kg ∘C. The latent heat of fusion of ice is...

A 5-gram ice cube at -2 degrees Celsius is dropped into 60 grams
of liquid water at 12 degrees Celsius. If the ice and water are
isolated from the environment, what is the final temperature of the
combined liquid water when all of the ice has melted and the
mixture reaches thermal equilibrium?

A 29.5g ice cube at -10 degrees celsius is place in a thermally
insulated container along with 1.000kg of water initially at 20.0
degrees celsius. determine the final temperature of the system and
the amount of heat acquired by the ice during the process and the
amount of heat lost by the warm water. PLEASE SHOW WORK AND
EQUATIONS USED. I'm struggling to find equations for heat gained,
lost, and final temp. thank you.

A 10 g ice cube at 0oC is melted in 100 g water
initially at 20oC. The equilibrium temperature of the
mixture is 10.93oC.
Calculate:
a) The heat lost by the water.
b) The heat gained by the melted water of the ice cube.
c) The heat absorbed by the ice to achieve melting.
