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.
To sum up, all Cherokee Trailhawks are towable behind an RV, and a Cherokee Latitude or Limited 4x4 can be if they are fitted with the optional Active Drive II 4x4 system. Our particular Limited 4x4 is not towable because it has the standard Active Drive I 4x4 system.
