A ball rolls down from the top of an incline with a height of 5 m high without slipping. The ball has a diameter of 0.2m. What are the ball’s translational speeds a) at the center of the ball, b) at the contact point on the ground, and c) at the top of the ball when it arrives at the bottom? What values of "c" do you expect for hollow/solid balls? Will the hollow ball be faster?

The Price of Baked Beans
As residents in the UK hunkered down at home to protect themselves from the spread of novel
Coronavirus they filled the pantries with toilet paper, sanitizing products and convenience foods.
Baked beans, one of the UK’s most enduringly popular convenience foods, are expected to
become scarce and expensive during the next months. The reason is unprecedented heavy rainfall
which has devastated crops in the main growing areas, the American state of Michigan and the
Canadian province of Ontario. A few weeks ago growers were expecting a record harvest but the
position is described now as catastrophic.
The price of a 100lb –bag of Canadian beans has soared from $27 to around $70, which
has added $0.60 to the retail price of a 15oz can previously costing between $1.50 and $1.20.
Moreover, the crop failure caused and unseemly scramble for supplies among big
canning firms such as Heinz and Crosse and Blackwell. Alternative sources being sought
includes South America, East Africa and even Romania.
Worldwide baked beans consumption is around 800,000 tonnes a year. The British eat a
healthy 80 000 tonnes, which represents 4 500 000 cans a day, with an annual retail value of
more than $200 million. The annual import bill is between $20 and $30 million.

How exactly does a business allow the budgeting process to trickle down?

• Water is boiled in a cup and put to cool down inside a room. The air temperature in the room is increasing linearly according to the function T_a(t) = 22 + 0.015t (t in minutes, T in Celsius). Assume Newton’s Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. The temperature of the water was checked after 8 minutes and it was 82 Celsius. Explain and graph T_a. Establish and solve an Initial Value Problem to express the water temperature as a time function, graph this function.
