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 Chevrolet Silverado pickup truck, along with its siblings the GMC Sierra and compact Chevy Colorado, can tow from 2,400 lbs. to more than 10,000 lbs. Engine size, type of transmission, rear axle ratio, cargo box size and the amount of torque a Chevy truck can generate are the keys to maximum towing capacity.
