While ice skating, you un-intentionally crash into a person. Your mass is 60 kg, and you are traveling east at 8.0 m/s with respect to the ice. The mass of the other person is 80 kg, and he is traveling north at 9.0 m/s with respect to the ice. You hang on to each other after the collision.
A. In what direction and at what speed are you traveling just after the collision?
B. What are the momenta of you and the other person before collision?

Astudent is working in a lab to determine how time affects impulse. the student keeps the force the same in each trial but changes the impact time. some data is shown.

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?

This is the number of complete movements of a wave per second.
