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.
  Yes. However, the trailer should not exceed the rated towing weight of the vehicle. There are several models of pop-up trailers that are towable for a Jeep Wrangler, CJ- â¦ 7, etc.The vehicle towing weight should be in the owner's manual--or you can call a Jeep dealer and ask them.here are 453.5924 grams in a pound. So 1/2 pounds equals 226.7962 grams. So the soda â¦ alone weighs about 226.7962 grams Add the cans weight of 14 grams to the average weight of the soda 226.7962 grams. Which means the average can of pop weigh 240.7962 grams or .5552 pounds.
