Mike (m = 40 kg) is riding his bike (m = 15 kg) at a velocity of +4.0 m/s. Mike decides to jump off his bike and achieves a new velocity of +5.0 m/s. Calculate the velocity of the bike after the collision.

Which sound characteristic is not affected by the relative motion of an object

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?

Avector of magnitude 2 cannot be added to a vector of magnitude 3 so that the magnitude of the resultant is a. zero b. 1 c. 3 d. 5 e. 7
