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.
Instructions. Look on the trailer's data plate to determine its gross trailer weight (GTW). Make sure it is safe to tow the trailer by confirming the GTW is less than the Enclave's towing capacity. The 2011 Buick Enclave is rated for a maximum tow of 4,500 pounds.
