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.
2014 Jeep Cherokee vs 2014 Jeep Grand Cherokee Engine. The Grand Cherokeeâs diesel engine is capable of towing up to 7,400 lbs. The 2014 Jeep Grand Cherokee is available in a choice of three engines. Standard is a 3.6-liter V-6 engine that creates 290 horsepower and 260 lb-ft of torque.
