A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of +16.7 m/s in a time of 20.7 s.
The combined mass of the boat and trailer is 594 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?
Reliable (marketing research) information is collected from questions (measurements) that are free from systematic or statistical error. An absence of systematic error implies that the respondents (i.e., the sampled people) who answer questions actually understand what the questions were asking.
