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.
The capable Jeep Â® Cherokee can tow up to 4,500 pounds so you can tow all kinds of gear. If you need outstanding efficiency and maximum towing capability, look no further than Cherokee. And, if your Cherokee is equipped with Jeep Â® Active Drive II or Active Drive Lock, you can flat tow your vehicle behind an RV.
