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 Buick Enclave is a base-luxury model that might be better suited getting groceries or taking the family to the movies than it would to a campground, but the standard 3.6L V-6 produces 288 horsepower and 270 lb-ft of torque. With the $525 towing package option, the Enclave is capable of hauling up to 4,500 pounds. A perfect pairing example: the Rockford Mini Lite 1905 trailer. Itâs a 20-foot fully appointed trailer tipping the scales at only 2,945 pounds. It sleeps four and has a full kitchen and bathroom.
