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.
Only vehicles with a maximum capacity of at least 5,000 lbs. are on this list: 1  Ford Super Duty Trucks â Fordâs Super Duty trucks encompass F-250, F-350, and F-450 models, with the F-450 having a maximum 5th wheel towing capacity of 32,500 lbs and a max 21,000 capacity with conventional trailer towing.
