A car moving at a speed of 25 m/s enters a curve that traces a circular quarter turn of radius 113 m. The driver gently applies the brakes, slowing the car with a constant tangential acceleration of magnitude 1.2 m/s^2. Required:a. Just before emerging from the turn, what is the magnitude of the car's acceleration?b. At that same moment, what is the angle q between the velocity vector and theacceleration vector?

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?
