Update: part A was: Use conservation of energy to calculate the linear speed of the yo-yo just before it reaches the end of its 1.5 m long string, if it is released from rest. v=1.2 m/s.Follow.e know linear KE=1/2*m*v^2 and rotational KE=1/2*I*w^2 where I is the moment of inertia and in this case it is I=mr^2. So....
We always recommend having at least a couple of thousand pounds of towing capacity in excess of what your trailer weighs, and our 4,300-pound test trailer was probably a fair representation of what people will be towing with a Grand Cherokee.
We would be towing it with a 2008 Honda Pilot, which has a towing capacity of 3500 lbs. It seems that a lot of the threads say you should leave some wiggle room and not pull all the way to the towing capacity. However, we live in the midwest and would most likely camp at most 4 hours away in pretty flat terrain.
