Afugitive tries to hop on a freight train traveling at a constant speed of 5.2 m/s . just as an empty box car passes him, the fugitive starts from rest and accelerates at a = 1.3 m/s2 to his maximum speed of 6.1 m/s , which he then maintains. how long does it take him to catch up to the empty box car? what is the distance traveled to reach the box car? express your answer to two significant figures and include the appropriate units.

The discovery that the universe appears to be expanding led to a widely accepted theory called a.) the big bang theory b.) the doppler effect c.) hubble’s law d.) solar nebular theory e.) the seyfert theory

Jackson is designing a new heater, and he wants to experiment with different thermally conductive materials. which of these materials would be useful in conducting heat?

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?
