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.
ANSWERED BY. 25 March 2016. The towing capacity of the 2012 Camry is 500kg if the trailer has no brakes and 1200kg if it does have brakes. Given your wanting to tow a small aluminium boat I assume your trailer doesn't have brakes, so the 500kg limit would apply.
