In a recent hockey game, one player (m=100kg) was
moving at a velocity of 8 m/s when he ran into another
player (m=300kg) who was at rest (v=0m/s). After the
collision, the two players were stuck together (moving with
the same velocity). What was their velocity after the
collision?

Select One:

A: 0 m/s
B: 2 m/s
C: 8 m/s
D: 4 m/s​

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Which statements did both aristotle and ptolemy assume? check all that apply.

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?
