Two vehicles are moving toward each other. The west bound vehicle has a momentum of 500 000 kg. kmh, while the east bound vehicle has a momentum of 250, 000 kg•km/h. If the two vehicle
collided without braking, which way will they continue to move after the collision? Draw a
diagram to illustrate your answer

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?

Cathy is pedaling down a steep hill on her bicycle and wants to be able to coast up the next hill, which is 25 meters high, without pedaling. cathy and her bicycle have a mass of 75 kg. assuming her bicycle is 100% efficient, what would her speed have to be?
