A chicken is waiting to cross a 5m, one way road, along which cars are travelling
at 40m/s. If the chicken can accelerate at 5m/s2 to a maximum speed of
5m/s, how big a gap in the traffic does she require in order to cross the road
without a car passing her during the crossing.
Depressed by its inability to solve physics problems, a chicken decides in end it
all in the traditional way. A bus will pass at precisely 12 o’clock, on a road parallel
to the field edge, which is 100m from the coop at the closest point. The bus
travels at 10m/s, and the chicken can run at 5m/s. What is the latest time that
the chicken can exit the coop?

Some Chickens are cooler than others
A large frozen chicken at -10 C is dropped into a pot containing an equal mass
of brine at 0C. After some time, the chicken has not thawed. What temperature
is the chicken, and what fraction of the chicken melts.
[Assume the brine has a freezing point of -15C and heat capacity of 3.2kJ/kg/K,
independent of concentration. Treat the chicken as water ice with heat capacity
2kJ/kg/K, latent heat of melting 334kJ/kg]

Unscheduled Pantechnion Incident
A farmer wishes to measure the width of a road. He releases a flock of 100
chickens simultaneously from one side of the road. These chickens are known
to cross roads directly at an average speed of 1m/s and standard deviation of
0.2m/s. after 5 seconds the experiment is abruptly ended by the sudden arrival
of a large lorry, at which point only 17 chickens have crossed the road.
Estimate the width of the road, and the error on your estimate.
A coop is demolished to make way for a 5MW wind turbine. One of the chickens flies
into space where it is annihilated in an unfortunate encounter with an antimatter
antichicken. How long does the wind turbine have to operate to generate the equivalent
amount of energy?
In a flap
A closed 1 tonne lorry is carrying 500kg of chickens to market. It has to cross a bridge
which can bear a maximum weight of 1.2tonnes. The driver attempts to lighten the load
by getting the chickens to fly up. Will this help?
Getting over it.50 chickens are walking across a 10m wide icy road at 2m/s. Being cautious birds, they leave enough gap between one another to stop at a deceleration rate of 1m/s^2. How long does it take them all to cross? On their return, enthused by the prospect of a feed, they decide to run across, at 5m/s again leaving enough space to stop. Now how long does it take them?
McChickenA spacechicken finds itself on the moon. How many chicken sandwiches contain enough energy to put it into orbit?
[ A typical chicken sandwich has 385 nutritional calories. One nutritional calorie is equivalent to an energy of 4.2 kJ. The radius and mass of the moon are 1738 km and 7.34 x 1022 kg respectively.]
