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.
Well looking at the towing capacity for the 2016 V6 Sorento, it is now at 5,000lb. But the 2.0 Turbo which has more torque is only rated at 3,500lb. So how is it that the V6 has a higher rating. More confusing is that the 2015 V6 is also only 3,500lb. Both 2015 and 2016 V6 are identical.
