A cart or dray (Aus. & NZ) is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people.
It is different from the flatbed trolley also known as a dray, (for freight) or wagon, which is a heavy transport vehicle with four wheels and typically two or more humans.
Over time, the term "cart" has come to mean nearly any small conveyance, including shopping carts, golf carts, gokarts, and UTVs, without regard to number of wheels, load carried, or means of propulsion.
The draught animals used for carts may be horses, donkeys or mules, oxen, and even smaller animals such as goats or large dogs.
Say I launch an object (a cart) up a frictionless inclined plane at an angle of 'theta' to the horizontal.
Question: What would be the acceleration of the cart right after it is launched?
My guess at the answer: 9.81*cos(theta)
since the cart is launched at an angle.
BUT I'm not sure...
