Acar is towing a boat on a trailer. the driver starts from rest and accelerates to a velocity of +15.2 m/s in a time of 22.3 s. the combined mass of the boat and trailer is 573 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?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
