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.
Towing capacity, sometimes called maximum towing capacity, is the maximum allowable weight that a vehicle can tow. Towing capacity is specified by the vÂ­ehicle manufacturer and can usually be found in the ownerâs manual. Some towing hitchesâ towing capacity exceeds that of certain cars and trucks, but that is because hitches can often fit on many different types of tow vehicles.
