As promised in another thread: Riddle me this, riddle me that...
There are two carts on the table. For each cart, there is a rope attached on one side to the cart and via a pulley it is hanging over the edge of the table. On the other end of one rope a 5 kg weight is attached and on the other rope a person pulls with a force corresponding to 5 kg. Which cart has the highest initial acceleration?
a. The cart with the weight.
b. The cart with the person.
c. There is no difference.
I think that the cart with the person pulling the rope will have the highest initial acceleration. This is due to the difference between force and thrust: the person pulling the rope immedialtly applies a thrust to the system, while gravitation does not.
Any thoughts, anyone?
