Adriver is traveling east on a dirt road when she spots a pothole ahead . she slows her car from 14.0 m/s to 5.5 m/s in 6.0 s. what is the cars acceleration? show the formula and how to work it out. you!

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

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?
