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.
Compatible with Jeep Grand Cherokees from model year 2011 on, the hitch receiver will not disappoint with its level of strength or durability. Check the owner's manual of your Jeep to make sure not to exceed its rated towing capacity. Mopar Item # 82212180AC. Class IV Trailer Hitch-OE Hitch in Kit includes bezel.
